A 0.5V 8bit 10Msps Pipelined ADC in 90nm CMOS

Abstract

A true low voltage 0.5 V 8 bit pipelined A/D converter is realized in 90 nm CMOS technology using regular Vtau devices. A cascaded sampling technique is used to combat the OFF leakage of the switches. The converter prototype occupies 0.85 mm2; operating at 10 Msps, it consumes 2.4 mW and achieves an SNDR of 48.1 dB with a 0.4 Vppdiff full-scale input.
