A 433 MHz 54 μW wake-up receiver that supports OOK/FSK/PSK demodulation schemes is proposed. Injection-locking and superregenerative reception provide the capabilities of demodulation and linear amplifications with superior sensitivity and high energy efficiency. For a data rate of 200 kbps and a BER <; 0.1%, the proposed receiver achieves sensitivity of - 80/-78/-77 dBm under OOK/FSK/PSK schemes, respectively. Further, incorporating a loop antenna with a reception of an injection-locked oscillator, the receiver features a low-power mode of 11 μW with an energy efficiency of 55 pJ/bit. A prototype receiver is fabricated in a 0.18-μm CMOS process with an active area of 0.45 mm2.

We present the implementation and experimental verification of the first complete digital logic library based on amorphous carbon (a-C)-coated curved-cantilever nanoelectromechanical (NEM) switch technology. Experimental results for sequential gates - latches and edge-triggered D flip-flops (DFF) - and combinational circuits (NAND, AND) are reported for the first time. The capability of the fabricated NEM switch device to store and maintain charge on internal parasitic capacitances during the off-state is confirmed through measurements of dynamic sequential cells. This complete logic library paves the road towards the development of NEM switch-based microprocessors for ultra-low power logic applications.

An inductive coupling technique for wireless interconnection of side-by-side chips within a package is presented. Data is transferred by using changes in magnetic field that occur when the current in coils on the chips is switched off. The circuit layout area and power consumption of transceivers have respectively been reduced to 1/3 and 1/6. A world-leading transmission rate of 1 Tb/s/mm2, which is faster by a factor of 3, has been achieved with a 0.18 μm CMOS test chip.

This paper presents a 5-50 Gb/s quarter-rate transmitter with a 4-tap feed-forward equalization (FFE) based on multiple-multiplexer (MUX). A bandwidth enhanced 4:1 MUX with the capability of eliminating charge-sharing effect is proposed to increase the maximum operating speed. To produce the quarter-rate parallel data streams with appropriate delays, a compact latch array associated with an interleaved-retiming technique is designed. Implemented in 65 nm CMOS technology, the transmitter occupying an area of 0.6 mm2 achieves a maximum data rate of 50 Gb/s with an energy efficiency of 3.1 pJ/bit.

High-voltage tolerant bi-state self-biasing output driver using cascade complementary latches in twin-well CMOS technology 采用级联互补锁存器的双阱CMOS技术的高容压双态自偏置输出驱动器

The design of a bi-state output buffer that can handle 5 times the supply voltage is presented. The use of self-biasing stacked devices driven by a cascade of complementary latches allows all devices to operate within the limits set by the technology, thus minimising any hot carrier injection and dielectric stress degradation. The presented voltage extension technique is scalable to larger and smaller external voltages and suitable for all twin-well technology feature sizes. The technique using the cascade of complementary latches is applied to the realization of a CAN output driver in a digital twin-well double-oxide 180nm technology featuring both 1.8V 180nm and 3.3V 350nm CMOS devices. The CAN driver consists of two bi-state drivers, which are both in high-impedance state during the CAN recessive state and in the high and respectively low state for the CAN dominant state. The realized prototype driver can handle external voltages between -3V and 16V and exhibits a 1.5V differential output swing on a 60Ohm load over the military temperature range compliant to the CAN automotive standard. To the best of our knowledge this is also the first realization of a CAN driver in a low-voltage digital CMOS technology.
设计了一种能处理5倍电压的双态输出缓冲器。使用由级联互补锁存器驱动的自偏置堆叠器件,允许所有器件在该技术设定的限制内运行,从而最大限度地减少任何热载流子注入和介电应力退化。所提出的电压扩展技术可扩展到更大或更小的外部电压,适用于所有双井技术特征尺寸。利用互补锁存器级联技术,在1.8V 180nm和3.3V 350nm CMOS器件的数字双阱双氧化物180nm技术中实现了CAN输出驱动器。CAN驱动器由两个双态驱动器组成,它们在CAN隐性状态时均处于高阻抗状态,在CAN显性状态时分别处于高、低状态。实现的原型驱动器可以处理-3V至16V之间的外部电压,并在符合can汽车标准的军用温度范围内,在60Ohm负载下显示1.5V差分输出摆幅。据我们所知,这也是第一次在低压数字CMOS技术中实现CAN驱动器。

This paper presents a DC-RF power inverter that efficiently synthesizes high-voltage RF waveforms directly from a battery voltage using thin-oxide CMOS switches. Instead of stacking transistors or employing large inductive transformation ratios, high output power is generated by switching individual class-D power amplifier (PA) cells in a 2-phase house-of-cards (HoC) topology to provide voltage addition of the cells outputs without exceeding device voltage ratings, effectively resulting in a solid-state RF impedance transformer. High-efficiency at backoff is then achieved by capacitively combining the output of two HoC networks nominally set to generate different amplitudes, enabling voltage-mode Doherty-like backoff without a bulky transmission line. The PA is implemented in 65nm bulk LP CMOS, operates from 4.8V, and provides a battery-to-RF efficiency above 40% at both 23dBm and 6dB backoff at 720MHz.
本文提出了一种DC-RF功率逆变器,该逆变器利用薄氧化物CMOS开关直接从电池电压有效地合成高压RF波形。与堆叠晶体管或采用大电感转换比不同,高输出功率是通过在两相卡屋(HoC)拓扑中切换单个d类功率放大器(PA)单元来产生的,从而在不超过器件额定电压的情况下为单元输出提供电压附加,从而有效地产生固态射频阻抗变压器。然后,通过电容性地组合两个名义上设置为产生不同幅度的HoC网络的输出,实现了高效率的回退,从而实现了电压模式的Doherty-like回退,而无需庞大的传输线。PA采用65nm体积LP CMOS实现,工作电压为4.8V,在720MHz的23dBm和6dB回退下,电池对射频的效率均高于40%。

A lower power and area efficient VP9 and multi-standard video decoder chip is first-reported for Android 4K TV. It supports prevalent MPEG-x, VP-x, RMx, WMV-x and H.26x series video standards in a single chip. Three high-throughput techniques, look-ahead re-mapping, early stage pipeline and dynamic-scheduled bus translation, are proposed. They cuts the processing times by 51.2% compared to the state-of-the-art design [4]. Moreover, two area-efficient techniques, hybrid backward probability update and tile-to-raster scan ordering, are designed to reduce the internal memory size by 10%. A mass-production chip is fabricated in a 28nm CMOS technology with an energy efficiency of 0.19nJ/pixel and an area of 2.6mm2. Compared to the dual-core decoder design [4], this work achieves the identical performance (4K@60fps) with single core which cut one-half of chip area.

A ZVS resonant receiver with maximum efficiency tracking for device-to-device wireless charging 一种ZVS谐振接收器,具有设备对设备无线充电的最高效率跟踪

A receiver for efficient wireless power delivery at 6.78MHz from smartphones to IoT devices has been designed in 0.18 μm CMOS. The receiver implements a technique to estimate the end-to-end efficiency and achieve maximum efficiency-point tracking (MEPT) across the charge cycle of a Li-ion battery without needing an explicit communication channel with the transmitter. The MEPT technique is tested using two rectifier topologies designed in the same process - the commonly used synchronous full-bridge and a resonant topology with ZVS for high efficiency. Adding MEPT to the full bridge receiver yields an estimated 7.9% savings in transmitter energy in fully charging a Li-ion battery on the receiver, while using the resonant rectifier with MEPT achieves 13.8% total savings in transmitter energy.
采用0.18 μm CMOS,设计了一种用于智能手机到物联网设备的6.78MHz高效无线电力传输的接收器。接收器实现了一种技术来估计端到端效率,并在锂离子电池的整个充电周期中实现最大效率点跟踪(MEPT),而无需与发射器建立明确的通信通道。MEPT技术使用在同一过程中设计的两种整流器拓扑进行测试-常用的同步全桥和具有高效ZVS的谐振拓扑。将MEPT添加到全桥接收器中,在对接收器上的锂离子电池进行完全充电时,估计可以节省7.9%的发射机能量,而使用带有MEPT的谐振整流器则可以节省13.8%的发射机能量。

This paper discusses some of the recent advances and challenges that lie ahead for Polymer Microwave Fibers (PMF). PMF is a communication concept that combines mm-wave chips, metal couplers and cheap plastic fibers. It has some unique benefits over copper wireline and optical which can give it a preferred solution for low-cost, low-weight robust high-speed data-communication such as automotive and industrial Ethernet, consumer-oriented connectivity, signal distribution and more.
