Method for analog-to-digital conversion of analog input signals
Abstract:
A pipelined analog-to-digital converter has an analog signal input. A first input sample-and-hold circuit is connected to the analog signal input. An amplifier is connected to an output of the first input sample-and-hold circuit. A second input sample-and-hold circuit has an input connected to the analog signal input in parallel to the first input sample-and-hold circuit. An AD/DA conversion path is connected to an output of the second input sample-and-hold circuit. A first output sample-and-hold circuit has an input connected to an output of the amplifier. A second output sample-and-hold circuit has an input connected to the output of the amplifier. The amplifier, the first output sample-and-hold circuit, the second input sample-and-hold circuit, and the AD/DA conversion path are part of a converter stage and outputs of the converter stage are inputs to a following converter stage.
