Abstract
A pipelined Analog-to-Digital Converter (ADC) comprising a number of stages, at least one of the stages includes a sample and hold circuit. The sample and hold circuit includes a first output connected to an input of a sub-ADC, an output of the sub-ADC connected to an input of a Digital-to-Analog Converter (DAC), an output of the DAC connected to a node, and a second output connected to the node. The sample and hold circuit is configured to independently scale a signal produced by the first output and a signal produced by the second output.
