Abstract
A multichannel ADC is fabricated on a single IC with each analog channel for concurrently processing input analogue signal in a pipelined manner and including a dual purpose intermediate amplifier for amplifying an input voltage to be converted and providing a reference voltage for use during conversion. A unique capacitor array reduces the area required to implement the convertors.
