Highly Linear Gm C based Sigma Delta Modulator [mt]
Ultra-low Power, Wide Bandwidth Continuous-time Sigma Delta Analog to Digital Converter Design
A. Abdelaal: Continues time delta sigma modulators (CTDS) have recently become the key device for broadband wireless and wireline communication. Due to there built in anti-aliasing filter and the ability to have relaxed sampling requirements the CTDS modulators are preferred over there discrete time counterparts ... [more]
