• Arrayable Voltage-Controlled Ring-Oscillator for Direct Time-of-Flight Image Sensors

Publication Year: 2017, Page(s):2821 - 2834
Cited by:  Papers (3)
| | PDF (4131 KB) | HTML

Direct time-of-flight (d-ToF) estimation with high frame rate requires the incorporation of a time-to-digital converter (TDC) at pixel level. A feasible approach to a compact implementation of the TDC is to use the multiple phases of a voltage-controlled ring-oscillator (VCRO) for the finest bits. The VCRO becomes central in determining the performance parameters of a d-ToF image sensor. In this p... View full abstract»

A novel triple-path PLL (TPPLL) is presented to compensate the VCO frequency drift caused by the large temperature variations meanwhile maintaining a stable bandwidth and good jitter performance. The proposed PLL architecture splits the VCO tuning loop into three paths as the proportional, the integral, and the temperature compensation (TC) path, respectively. The feed-forward TC path with a large... View full abstract»

• A Third-Order MASH $\Sigma \Delta$ Modulator Using Passive Integrators

Publication Year: 2017, Page(s):2871 - 2883
Cited by:  Papers (1)
| | PDF (2749 KB) | HTML

This paper presents a MASH ΣΔM using only passive integrators and simple differential pairs as low-gain blocks. Instead of high-gain power hungry op-amps it uses more processing gain from the comparator (1-bit quantizer) as a part of the loop gain. The proposed approach allows the design of a continuous-time, 2-1 MASH ΣΔM in a 65-nm CMOS technology occupying an area of just 0.027 mm2. M... View full abstract»

Nonvolatile computing has been proven to be effective in dealing with power supply outages for on-chip check-pointing in emerging energy-harvesting Internet-of-Things applications. It also plays an important role in power-gating to cut off leakage power for higher energy efficiency. However, existing on-chip state backup solutions for D flip-flop (DFF) have a bottleneck of significant energy and/o... View full abstract»

Supply-voltage reduction in digital circuits beyond the minimum energy per operation point is advantageous for supply-voltage-constrained applications and can help to considerably reduce standby power consumption. Schmitt trigger (ST) logic allows for ultra-low voltage (ULV) operation; hardware implementations with supply voltages as low as 62mV have been demonstrated. In this paper, a systematic ...
