摘要
This paper presents an 8-bit, 80MS/s Successive Approximation Register analog-to-digital converter (SAR ADC) with 2bit/cycle structure for sensor application. By using two capacitor-DAC arrays, S-DAC and R-DAC, the proposed SAR ADC can obtain 2-bit in one comparison cycle. With split-capacitor structure and monotonic switching strategy, two DACs reduce the number of capacitors and save the ADC power consumption. The proposed asynchronous control logic speeds up the ADC. The proposed ADC achieves 46.17dB SNDR at 80MS/s rate with 1.8V supply voltage in 180nm CMOS process.
