The design of a 1.5 V, 10-bit, 10 M samples/s low power pipelined analog-to-digital converter

Abstract

An experimental low-voltage low-power pipelined analog-to-digital converter is designed and presented in this paper. The power consumption is efficiently reduced by using switched operational amplifiers and dynamic comparators. This chip is designed in a 0.35 /spl mu/m CMOS process. The core area occupies 1450 /spl mu/m/spl times/1100 /spl mu/m. The HSPICE simulation results show that the resolution of this design is 10-bit; the sampling rate is 10 MHz; the peak SNDR is 66 dB, and the power consumption is 15 mW at 1.5 V supply voltage.
