Abstract
Pulse generators include a delay circuit that is responsive to an input signal. The pulse generators also include an output circuit that is configured to generate an output pulse signal in response to the output of the delay circuit. In these pulse generators, the delay circuit has a variable delay that increases proportional to increases in a power supply voltage. Sense amplifiers that include these pulse generators are also provided.
