We propose complete technology-design-system co-optimization method in which power, performance, thermal, area and cost metrics are all simultaneously optimized from transistor to mobile SOC system level. This novel method, Unified Technology Optimization Platform using Integrated Analysis (UTOPIA), incorporates thermally limited performance, wafer process complexity and die area scaling model in addition to author's previous transistor-interconnect optimization method. Thermal model in UTOPIA evaluates/optimizes device and technology parameters not only for peak frequency but also for sustained performance after thermal throttling. Optimum N7 technology is selected using proposed UTOPIA method, showing significant overall gain over N10 technology.

This paper describes an 8.5-11.5 Gb/s transceiver with a dual path receiver and a voltage-mode transmitter. The RX can operate either in ADC mode for complex loss channels such as optical multimode fiber or in DFE mode for copper-based backplane links. The ADC path implements a 2X interleaved 6-bit rectifying flash ADC using a programmable gain amplifier (PGA) with controlled bandwidth and peaking, comparator pipelining, and super-source follower circuit techniques. The LRM optical sensitivity requirements are met with a > 6 dB margin while achieving an ENOB of 4.59 bits at a 5 GHz input frequency. The TX/RX DFE path achieves copper channel loss compensation of 38 dB with BER <; 10-12 at 11.5 Gb/s consuming 46mW from a 0.9V supply. The TX/RX ADC path consumes 125 mW at 10.3125 Gb/s. The TX/RX occupies 0.56 mm2 in a 28nm standard CMOS process.

Vmin measurements in 28nm FDSOI technology on 128Mb SRAM bitcells from -40°C to 125°C are reported in this paper. Adding the silicon ageing behavior and the process variability, we have developed a complete model and demonstrated end-of-life SRAM Vmin of 0.6V and 0.5V on 20Mb with 0.120μm2 and 0.152μm2 bitcells, respectively. This is the first report of a such extensive SRAM Vmin assessment at the 28nm node. The construction of write limited bitcells, combined with write assist design technique, was found to be the most efficient way to achieve ultra low Vmin in 28nm FDSOI technology. In addition, Vmin retention below 0.4V is demonstrated in 0.120μm2 bitcells, leading to the enablement of ultra-low leakage bitcells with 2pA/cell in retention mode.

A 16-channel machine learning digitizing interface embeds Inner-Product calculation within a Delta-Sigma Modulator (IPDSM) array canceling quantization noise and noise shaping the multiplicand. The prototype, with 16 independent IPDSM channels occupies a core area of 0.95mm2 in 65 nm CMOS. Each channel performs up to 100M multiplications/s. The system is demonstrated with a standard machine learning scheme for image recognition. It achieves the same classification accuracy for the MNIST set of hand-written digits as with the same algorithm on floating point DSP.

Motor Control may not be as trendy as say IoT, but it cannot be denied that the application areas of late have been much more interesting. The growing popularity of drones, electric vehicles such as the Tesla, mobility vehicles like electric bikes or the allure of hover-boards have seen an explosion of electric motors. But changes are also happening in the more traditional industrial sector of motor and servo drives. The demand for cost and energy efficiency is driving the need for new system topologies and greater integration levels. Devices now have to integrate communications with traditional control. Integrated Safety and Security are now part of the mix. The Motor Control device of today is vastly different then 10+ years ago and the challenges are much greater, requiring a broader set of design skills.

We describe a 14-bit 2.5GS/s non-interleaved pipelined ADC that relies on correlation-based background calibrations to correct the inter-stage gain, settling (dynamic), kick-back and memory errors. A new technique is employed to inject a large dither signal on the input to dither the non-linear kick-back on the ADC driver, and another large dither signal is injected to dither any residual non-linearity in the pipeline. In order to correct the effect of aging on the comparators, a new background calibration technique is employed to correct the comparator offsets. The ADC is fabricated as a dual in a 28nm CMOS process. An optional interleaved mode is provided, where the two ADCs on chip are time-interleaved to obtain a single 14-bit 5GS/s ADC. Background calibration of offset and gain mismatch and fixed calibration of timing mismatch between the two channels are implemented on chip.

This paper presents an active transmitter (TX) cancellation scheme for FDD that synthesizes a replica of the TX current in shunt with the receiver (RX), virtually shorting out the TX signal for the RX while having minimal impact on TX insertion loss. The prototype in 65nm CMOS demonstrates >50dB cancellation of a +12.6dBm peak 20MHz modulated TX signal. A receiver integrated on the same prototype is able to down-convert the RX signal at 40MHz offset with <;4.3dB noise figure (NF) degradation in the presence of the residual TX.
