ABSTRACT:
A switched-capacitor gain stage suitable for use with a pipelined analog to digital converter (“ADC”) is capable of processing two or more input channels. The analog input voltages from the multiple channels are concurrently sampled (every other clock phase), and the gain stage processes the samples using a double sampling technique, generates residual voltage samples (every clock phase), and generates digital outputs for the multiple channels in an alternating manner. The gain stage provides equal input loading for the input stages, which enhances the performance of the ADC.
