MINLP Based Power Optimization for Pipelined ADC

Abstract

This paper proposes a Mixed Integer Non-linear Programming (MINLP) based optimization algorithm to design power optimized pipelined ADC. For a given specification the proposed algorithm gives stage resolution and sampling capacitor per stage that minimizes the total power consumption. Closed form expressions of the power consumption of each stage were derived and used as objective function. Pipelined ADCs of various specifications, viz., 10-bit, 12-bit, and 16-bit, were designed and validated using this algorithm.
