Abstract:
A low latency comparator circuit with a local clock circuit is disclosed. A comparator circuit configured to compare a first input signal to a second input signal. The comparator circuit includes at least one regenerative latch circuit having a first and second inputs configured to receive the first and second input signals, respectively. The comparator circuit further includes a clock circuit configured to generate and provide a clock signal exclusively to circuitry in the comparator circuit, including the at least one regenerative latch circuit. At least one output latch circuit coupled to the at least one regenerative latch circuit and configured to provide a first output signal indicative of a comparison of the first and second input signals.
