Abstract
A sigma-delta modulator and method for converting an input voltage such as an analog signal into a digital signal is presented. The modulator may be used as an analog-to-digital converter (ADC). The modulator has a plurality of bias transistors with at least one p-type transistor and at least one n-type transistor. The modulator receives a bias voltage, wherein each bias transistor receives the same bias voltage. This sigma-delta modulator results in reduced power consumption.
