Abstract
A pipelined ADC with under-sampling technique is proposed. Under SMIC 0.35 um 1P6M process, the performance of SNR reaches nearly 66 dB with the condition that the sampling rate is 62.5 MHz and the input frequency is scanned from 1 MHz to 76 MHz except the Nyquist point. The typical power consumption is about 90 mW. Compared with Nyquist sampling, this design has lower power and less die area.
