A high-speed algorithmic ADC

Abstract

A method for realizing high-speed algorithmic analogue-to-digital converter (ADC) is presented in this paper. The realization method based on the proposed absolute function circuit, which performs a low-distortion in the transfer characteristic, is utilized. The proposed ADC is simple, small in size and suitable for implementing a high-resolution ADC. Performances of the proposed circuit are discussed in detail and confirmed through Cadence Spectre simulation results.
