摘要

This paper describes the analysis, design, and experimental results of a 12-b, 60-MSample/s analog-to-digital converter (ADC). This ADC is based on a cascaded folding and interpolating architecture. The ADC is optimized for digital telecommunication applications. The cascaded folding and interpolating ADC architecture is introduced, optimizing the overall performance of this converter. The integrated track and hold amplifier enables an SNR<66 dB and a THD>72 dB, measured over an analog input signal bandwidth of 70 MHz. The ADC is realized in a 13-GHz, 1-/spl mu/m BiCMOS process and measures 7 mm/sup 2/, while dissipating 300 mW from a single 5.0 V supply.
