ABSTRACT:
An analog-to-digital converter (ADC) of a radio receiver can consume a relatively large amount of power. It is typically desirable to minimize power consumption, particularly with battery-powered devices, such as in wireless receivers. In certain conditions, the effective number of bits (ENOB) required from an ADC of a receiver can vary. The power consumption of certain ADC topologies, such as pipelined converter topologies, can vary with the number of bits. One embodiment dynamically varies the ENOB of an ADC to more optimally consume power. This can extend battery life.
