摘要
A systematical design analysis of a 10-bit 50MS/s pipelined ADC is presented. With an opamp-sharing technique, the power consumption is reduced drastically. Simulated in a 130-nm CMOS process, it achieves a 58.9dB signal-to-noise ratio (SNR), a 9.3 effective number of bits (ENOB), 64dB spurious free dynamic range (SFDR) with a sinusoid input of 4.858-MHz 1-V-pp at 50MS/s, and consumes less than 24 mW from a 1.2-V supply.
