Classification: CPC H | IPC H

Claim 13:
14. A method for operating a self-clocked dynamic comparator, the method comprising:
comparing an input voltage (VIN) and an adjusted reference voltage (adjusted VREF) by a pre-amplifier (PRE-AMP);
outputting an enable (TRI) signal by the PRE-AMP, wherein the TRI signal is based on a comparison between the VIN and the adjusted VREF;
comparing the TRI signal and one of a first rail-to-rail output (OUT+) signal and a second rail-to-rail output (OUT−) signal by an AND gate;
outputting a clocking (CLKsf) signal by the AND gate;
receiving the VIN, a reference voltage (VREF) and the CLKsf signal by a latch; and
outputting the OUT+ signal and the OUT− signal by the latch,
wherein cycles of the CLKsf signal cause the latch to dissipate energy.
