Abstract
Switched capacitor notch filter circuits are disclosed. An example switched capacitor notch filter circuit described herein includes a switched capacitor amplifier to receive an input signal and a first feedback signal, to amplify the input signal and the first feedback signal, and to output an output signal, a first integrator to receive the output signal and a second feedback signal, to integrate the output signal and the second feedback signal, and to output the first feedback signal, a second integrator to receive the first feedback signal, to integrate the first feedback signal, and to output the second feedback signal, a sample and hold to receive the output signal, to periodically store a value of the output signal, and to output the value of the output signal, and a first switch to couple the sample and hold to the output signal when the sample and hold is to store the value of the output signal and to isolate the sample and hold from the output signal when the sample and hold is to output the value of the output signal.
