Use of chopper-notch modulator in chopper amplifiers for replica images cancellation [PDF]
2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008 A method for cancelling the replica image limiting the chopper stabilization technique is presented. The modulation of the 1/f noise at the chopping frequency and its multiple are conventionally reduced by a low-pass filter and, possibly by a notch filter.
