A 4–10 bit, 0.4–1 V Power Supply, Power Scalable Asynchronous SAR-ADC in 40 nm-CMOS with Wide Supply Voltage Range SAR Controller
Summary :
This paper presents a wide range in supply voltage, resolution, and sampling rate asynchronous successive approximation register (SAR) analog-to-digital converter (ADC). The proposed differential flip-flop in SAR logic and high efficiency wide range delay element extend the flexibility of speed and resolution tradeoff. The ADC fabricated in 40 nm CMOS process covers 4–10 bit resolution and 0.4–1 V power supply range. The ADC achieved 49.8 dB SNDR and the peak FoM of 3.4 fJ/conv. with 160 kS/sec at 0.4 V single power supply voltage. At 10 bit mode and 1 V operation, up to 10 MS/s, the FoM is below 10 fJ/conv. while keeping ENOB of 8.7 bit.
