Noise-cancelling switched-capacitor (SC) filtering technique
Authors:Lam  KKK Copeland  MA
Affiliation:Carleton University, Department of Electronics, Ottawa, Canada;
Abstract:A method of reducing the 1/f noise in SC filters is shown using an initialising technique. This technique also removes the input offset of the operational amplifier, and thus gives an offset-free SC building block. Experimental results for a first-order lowpass filter illustrating the above are presented.
