Abstract:
A circuit, which is usable in a flash analog-to-digital converter, includes a first switch configured to provide a first reference voltage to a first reference node responsive to a first control signal and a second switch configured to provide the first reference voltage to a second reference node responsive to a second control signal. A third switch is coupled to the first switch and is configured to provide a second reference voltage to the first reference node responsive to a clock signal. Further, a fourth switch is coupled to the second switch and configured to provide the second reference voltage to the second reference node responsive to the clock signal.

Claim (Index 1):
A flash analog-to-digital converter (ADC), comprising:\n a zero crossing comparator configured to compare an input analog voltage to a zero reference voltage; a flash converter comprising a plurality of comparators, wherein each of the plurality of comparators receives a comparator reference voltage and wherein each of the plurality of comparators is configured to compare the input analog voltage to each of the plurality of comparators reference voltages respectively; and a reference voltage control circuit configured to: responsive to an output signal from the zero crossing comparator, selectively switch a first reference voltage and a second reference voltage to a first reference node and a second reference node of the flash converter; and switch the second reference voltage to the first reference node and to the second reference node after receipt by the flash converter of an edge of a clock to cause the flash converter to begin using voltages on the first and second reference nodes and the input analog voltage to generate a flash converter output; wherein the comparator reference voltage for each comparator in the plurality of comparators is generated based on voltages on the first and second reference nodes.
