Abstract
An improved back gate switched sample and hold circuit includes a sample and hold channel including a sample switch having a back gate and a storage element; a back gate circuit for controlling the back gate of the sample switch; and a first attenuator circuit for scaling the input signal from a low impedance source for delivery to the sample switch and a second attenuator circuit responsive to the input signal from the low impedance source to independently drive the back gate circuit and isolate any distortion of the input signal in the back gate circuit from affecting the input signal in said sample and hold channel.
