Abstract

A 10b opamp-sharing pipeline A/D using current-reuse OTAs is presented. The current-reuse OTA, with two NMOS differential inputs operating in opposite phases, facilitates opamp-sharing between consecutive stages, minimizing power consumption. Constant transistor biasing ensures no loss of settling time from power-on delays. The A/D is fabricated in a 0.18μm CMOS process and occupies active area of 0.7mm2. At 50MS/s, maximum SNDR of 58dB (ENOB=9.3b) is obtained with 9.2mW analog power consumption on a 1.8V supply.
