ABSTRACT:
Methods and circuit embodiments are disclosed for implementing an improved signal path for a sample-and-hold output. In exemplary embodiments, a sample-and-hold signal path for use in a pipelined ADC includes a sample-and-hold circuit configured to operate in two distinct phases. The sample-and-hold circuit includes an input node, an output node, and a power supply node. The power supply node is configured to power down the op amp during one phase and power up the op amp during the other phase. The sample-and-hold stage is configured to provide output during one phase only. Other aspects of the invention include embodiments in which a sample-and-hold stage signal path in a pipelined analog-to-digital converter is configured to accommodate a plurality of parallel outputs.
