Abstract: A sampling circuit uses an input stage to sample an input signal and a secondary evaluation stage to maintain the output state of the input stage. Once the input stage transitions at a clock transition, the secondary evaluation stage uses regenerative feedback devices to hold the state to help ensure the sampling circuit only switches once during an evaluation.
