Abstract :
This paper describes the design of a 10-bit, 40-MSample/s analog-to-digital converter (ADC) based on a cascaded folding and interpolating architecture. The folding and interpolating factors are optimized for low power. The ADC features balanced circuit design, a newly developed shifted averaging technique, and stacked circuits for analog and digital folding. The untrimmed ADC dissipates 65 mW from a single 5-V supply. The fully differential ADC achieves 9.2 effective bits for a 1.6-Vpp input signal. Its resolution bandwidth is 20 MHz. The ADC is realized in a 7-GHz, 0.6-μm BiCMOS process and measures 0.8 mm2
