Abstract:
A multibit flash quantizer circuit, such as included as a portion of delta-sigma conversion circuit, can be operated in a dynamic or configurable manner. Information indicative of at least one of an ADC input slew rate or a prior quantizer output code can be used to establish a flash quantizer conversion window. Within the selected conversion window, comparators in the quantizer circuit can be made active. Comparators outside the conversion window can be made dormant, such as depowered or biased to save power. An output from such dormant converters can be preloaded and latched. In this manner, full resolution is available without requiring that all comparator circuits within the quantizer remain active at all times.

Claim (Index 11):
A method of operating a reduced power analog-to-digital converter (ADC) circuit, the method comprising:\n receiving, using a quantizer circuit, a sample of an analog input signal, the quantizer circuit including:\n a plurality of comparator circuits, each comparator circuit configured to compare the sample to a reference voltage associated with a corresponding comparator circuit and generate a corresponding digital output signal; and \n an output configured to generate a digital output code representing the analog input signal; \n receiving, using at least one comparator circuit, a respective power control signal to cause the at least one comparator circuit to enter and exit a reduced power state; and using the digital output code of the quantizer circuit to determine a subset of the comparator circuits to receive the power control signal and enter the reduced power state.
