Abstract
A temperature-stabilized 12-bit single-channel
successive approximation regi ster (SAR)-assisted pipelined
analog-to-digital converter (ADC) running at 1 GS/s with
Nyquist signal to noise and distortion ratio (SNDR) above 60 dB
is presented. The ADC uses a three-stage (4 b-4 b-6 b) SAR-
assisted pipeline hybrid architecture to achieve an attractive
energy efficiency along with an extended sampling rate.
