Abstract
In described examples, a circuit includes an integrator. The integrator receives an input signal. A first sampling network is coupled to the integrator and generates a signal voltage. A second sampling network is coupled to the integrator and generates a pixel sampled noise voltage. The pixel sampled noise voltage generated in a previous cycle is subtracted from the signal voltage generated in a current cycle to generate a true signal voltage.
