Abstract
Various embodiments of the present invention provide systems and circuits that provide for conversion of analog signals to digital signals. For example, various embodiments of the present invention provide pipelined analog to digital converters. Such converters include a sub-converter and a residue amplifier. The sub-converter receives an analog input, and provides a digital representation of the analog input including a number of bits. A gain of the residue amplifier is controlled by selectably setting a group of switches. Each of the number of bits output from the sub-converter electrically controls a respective one of the switches.
