High speed Continuous-time Delta Sigma Modulators for Wide-band Applications: A review paper

Abstract

This paper presents a review of high speed continuous time delta sigma modulators (CTDSM) designed for wideband applications. It analyzes different trade-offs involved in its design and choices available at architectural level suggesting the recipe for optimized design of wideband CTDSMs. It also discusses various design techniques used in the design of wideband CTDSMs and compares the performance of state-of-the-art wideband CTDSMs. This paper can serve as a starting point for the design of a low power wideband CTDSM.
