ABSTRACT:
A sample and hold circuit including a plurality of input signal sampling switches using native NMOS transistors in combination with switched bulk PMOS transistors. The input signal sampling switches input a differential input signal and output an intermediate differential signal. A plurality of capacitors are connected to the intermediate differential signal. A plurality of summing junction switches receive charge stored on the plurality of capacitors, and output a differential sampled and held charge to the summing junction. The plurality of input signal sampling switches include first, second, third, and fourth switches each having an input and an output. Inputs of the first and third switches are connected to a first voltage of the differential input voltage. Inputs of the second and fourth switches are connected to a second voltage of the differential input voltage. Outputs of the first and second switches are connected together and to an input of a first capacitor of the plurality of capacitors. Outputs of the third and fourth switches are connected together and to an input of a second capacitor of the plurality of capacitors.
