A 90nm CMOS 1.2V 10b power and speed programmable pipelined ADC with 0.5pJ/conversion-step

Abstract

A 10b pipelined ADC with programmable speed and power achieves a power efficiency of 0.5pJ/conversion-step for sampling frequencies between 25 and 100MHz. Measurements show an ENOB of 9.3b, ERBW exceeding 100MHz, and THD<-65dB with a supply voltage of 1.2V. Chip area is 0.3mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> in a 90nm digital CMOS process
