Abstract

A programmable, quantization error spectral shaping, alias-free asynchronous analog-to-digital converter (ADC) is provided. The ADC can be used for clock-less, continuous-time digital signal processing in receivers with modest Signal to Noise-plus-Distortion Ratio (SNDR) requirements and a tight power budget.
