In low voltage SRAM for IoT application, although static noise margin (SNM) and write margin (WM) decide VMIN, Icell / Ioff ratio and Icell are also important in order to keep performance and achieve better operating efficiency. We propose a new mixed Vth RP design which can achieve better Icell and Icell / Ioff ratio. Furthermore, combination of the proposed mixed Vth and boosted read wordline (RWL) scheme improves the worst case bitline delay time by 72.3% at 0.45V. In the measurement results, we confirmed a minimum operating voltage (VMIN) for the 64 Kb SRAM of 0.370 V with 99% yield at room temperature.

This paper presents an ultra-high-performance neural network engine fabricated in a 65nm CMOS technology. The 0.9mm2 core relies on an energy-efficient resonant clock mesh running at 5.5GHz to achieve 0.76 8-bit TOPS, improving throughput by over 4x, area efficiency by over 8×, and energy-delay-area product by over 1.8× compared to previous state-of-the-art neural network designs. Achieving a charge recovery rate of 63%, the resonant clock mesh enables the deployment of a deeply-pipelined stream architecture and high-speed stream buffers with a sub-5W power consumption.

This paper presents an area-efficient and fast-response CMOS Hall sensor system for a camera autofocus system. The prototype comprises of a Hall sensor and a capacitively-coupled instrumentation amplifier (CCIA). The Hall sensor adopts the spinning current technique to mitigate the Hall element offset. In the CCIA, the T-capacitor network is employed considering the capacitor matching requirement and the chip area. The amplifier offset is further suppressed by a ripple-reduction loop. This chip is measured with Helmholtz coil, Solenoid, and NMR system. Implemented in a 0.18-μm CMOS process, it achieves 564 μTrms in 180-kHz BW. The linearity error is < 0.5% over ±100-mT range. The power consumption is 1.19 mW, and the area is 0.12 mm2.

This paper presents a calibration scheme for reference error caused by signal dependent switching transient in a high speed SAR ADC. The scheme has a little hardware overhead, which is not dependent on the type of the input signal and is able to run in the background without interrupting the ADC's normal operation. The calibration along with the SAR ADC are implemented in a 65 nm CMOS and the measurement results show that the proposed scheme effectively improves the SNDR of an 11b SAR ADC by ∼9 dB. The calibration allows the placement of only 3 pF decoupling capacitance in the reference voltages. The prototype achieves 100 MS/s sampling rate with a total power consumption of 1.6 mW at a 1.2 V supply. Plus, it exhibits a 59.03 dB and 60.4 dB SNDR at Nyquist and low input frequency, respectively, yielding a Walden FoM@Nyquist of 21.9 fJ/conv.-step. The total core area is 0.011 mm2 which includes the decoupling capacitor.

A discrete time single loop 2nd order 5-bit ΔΣ modulator is implemented in 65nm CMOS for digital audio and sensor applications. We propose a power efficient integrator based on periodical-reset dynamic amplifier without static current consumption. A passive inter-stage sampling method is proposed which prevents active buffer. A 3-D capacitance layout implementation method is employed to saving the chip area. The prototype modulator has 91.2 dB peak SNDR in 24 kHz and consumes only 94μW from a 1-V supply, achieving a FOM of 66.2fJ/conv. The active core area is only 0.11mm2.

We demonstrate a low-power wireline transmitter with 2-tap pre-emphasis in which serialization is achieved by toggling serializer with data transition information extracted from parallel input data. This novel technique of serialization provides significantly reduced power consumption since it does not need the short pulse generation block required in the conventional serializer. In addition, the same data transition information can be directly used for implementing 2-tap pre-emphasize and, consequently, the need for the additional serializer required in the conventional pre-emphasis circuits can be eliminated, resulting in further reduced power consumption. A prototype transmitter realized in 65nm CMOS technology achieves energy efficiencies of 0.202 pJ/bit at 5 Gb/s and 0.3 pJ/bit at 8 Gb/s for 150 mVpp,d output voltage swing without pre-emphasis, and 0.252 pJ/bit at 5 Gb/s and 0.333 pJ/bit at 8 Gb/s with 2-tap pre-emphasis providing 6-dB equalization gain. To the best of our knowledge, these are the lowest energy efficiencies achieved for wireline transmitters realized in 65nm CMOS technology.

A highly linear trans-impedance amplifier TIA is proposed to meet stringent linearity requirements of SAW-less frequency-division duplexing (FDD) LTE receivers with 20MHz channel bandwidth. In the proposed solution the operational amplifier is compensated exploiting the passive feedback network in order to achieve wide bandwidth and low power dissipation. The prototype in 28nm CMOS achieves 14dB of gain with 20MHz bandwidth and features 46 dBm IIP3 and 12μV in-band noise, with 5.4mW power dissipation and a filter FOM of 183 dB.

A highly integrated, high-voltage dual-mode boost converter is presented for solid-state drive (SSD) applications, where standby mode efficiency with < 500 μA load is as critical as active mode efficiency with > 100 mA load. To enhance efficiency in light load condition and to achieve wide operation load range, loss minimization by balancing conduction and switching loss is adopted and dynamic power gating scheme is applied for PFM mode operation. Moreover, robust dual mode operation is implemented with time-based control scheme, which enables operation with lower peak current for optimal loss balancing. The proposed converter is fabricated in 130 nm CMOS process with an area of 1.7 mm2. The measured efficiency for supplying 12 V output from 5.5 V input is 91% at its peak and 85% with extremely light load of 200 μA. It also achieves wide load range of 34.6 dB for > 85% efficiency and 18.8 dB for > 90% efficiency.
