Abstract :
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.
