Abstract

In this article, a novel 10-bit two-step flash A/D converter architecture based on the threshold inverter quantization technique, TIQ is presented. The simulation results include 1.5V analog input range, 30 MHz input bandwidth, and 250 mWatts of power consumption at maximum sampling rate of 500 Ms/s. The process parameter and temperature variation analysis of the converter is especially included. The DC simulation results show linearity measures of less than 0.1 LSB DNL and INL for each 5-bit flash core. The active chip area is 1.4mm² in 0.5mum CMOS technology
