Abstract
A self calibrating algorithmic analog-to-digital converter is disclosed for which the gain of the conversion loop is precisely adjusted and controlled by an array of switched capacitors such control being stored in a latch. The offset of the gain stage is reduced by reducing the amount of charge injected from the gate of the input zeroing MOS switch.
