An analog-to-digital converter including a quantizer and a residue generator, both of which sample an input voltage in parallel. The sampling characteristics of each of the residue generator and the quantizer are designed to substantially match one another. This converter may be used as a low-power ADC front-end circuit that does not require a dedicated sampleand-hold circuit. The front-end circuit consists of two substantially-matched sampling networks, one for the residue generator and the other for the quantizer, inside the first stage of the converter.
