Abstract
A flip-flop circuit includes a charge injection module, a sense amp module, and a latch module. The charge injection module is configured to, in response to a clock signal, selectively provide electrical charge from a power supply to a first node. The sense amp module is configured to adjust a voltage of a second node in response to detecting a voltage of the first node crossing a threshold while the charge injection module is providing the electrical charge to the first node. The latch module is configured to in response to the clock signal, store a value based on a voltage of the second node. The latch module is also configured to provide the value as an output of the flip-flop circuit.
