Abstract
An input driven self-clocked dynamic comparator, and associated systems and methods are described herein. In one embodiment, self-clocked dynamic comparator, includes a latch configured to receive an input voltage (VIN), a reference voltage (VREF) and a clocking (CLKsf) signal, and configured to output a first rail-to-rail output (OUT+) signal and a second rail-to-rail output (OUT−) signal. The self-clocked dynamic comparator also includes a pre-amplifier (PRE-AMP) configured to output an enable (TRI) signal based on a comparison between the VIN and an adjusted VREF. The self-clocked dynamic comparator further includes a pre-amplifier (PRE-AMP) configured to output an enable (TRI) signal based on a comparison between the VIN and an adjusted VREF, and a logic gate configured to receive the TRI signal and one of the OUT+ signal and OUT− signal, and configured to output the CLKsf signal. The cycles of the CLKsf signal cause the latch to dissipate energy.
