Correlated double sampling technique for continuous-time filters

A correlated double sampling technique, applicable to continuous-time active-RC filters, is proposed. It provides suppression of DC offset and 1/f noise, and performs gain boosting and level shifting for the opamps used. A biquad lowpass filter is described to demonstrate the application of the tech...

Summary:A correlated double sampling technique, applicable to continuous-time active-RC filters, is proposed. It provides suppression of DC offset and 1/f noise, and performs gain boosting and level shifting for the opamps used. A biquad lowpass filter is described to demonstrate the application of the technique.
