摘要

This thesis presents a single-channel 2 5-bit/cycle 10-bit 160-MS/s successive-approximation register (SAR) analog-to-digital converter (ADC) In comparison with the conventional 2 5-bit/cycle SAR ADC the proposed input level shifting technique saves one sub-digital-to-analog converter (sub-DAC) and relaxes the requirement on resolution for the other sub-DACs In addition the proposed digital code error correction provides a wider error tolerance range by a compact digital design The proposed ADC was fabricated in TSMC 90-nm CMOS standard 1P9M process and occupies 262 8 μm × 420 μm active area At 1-V supply and 160-MS/s sampling rate the measured peak signal-to-noise and distortion ratio (SNDR) is 53 23 dB The resultant effective number of bits is 8 55 bits with power consumption of 1 97 mW The figure-of-merit (FoM) is 32 9 fJ/conversion-step
