A sample and hold circuit in one aspect includes first and second switches. The first switch can be coupled to receive an input signal and to sample the input signal using a first capacitor. A first leakage current flows between first and second conductive terminals of the first switch and accumulates as a first leakage charge in the first capacitor. A second leakage current flows between the first and second conductive terminals of the second switch and accumulates as a second leakage charge in the second capacitor. An offset circuit produces a compensated sampled value by subtracting a quantity from a signal developed in response to the held sampled signal and charge accumulated through the first switch, wherein the quantity is developed in response to the accumulated leakage charge in the second capacitor.
