Abstract
An apparatus includes a clock generator configured to generate a series of new clock pulses, the clock generator having an input port for receiving input clock pulses, an output port for delivering the new clock pulses to a target circuit that uses the new clock pulses to determine at least a start time or a stop time of a signal generated by the target circuit, and, a pulse delay for governing the width of the new clock pulses, the delay including circuits that produces longer delays for faster corners.

An apparatus comprising:
- a clock generator to generate a series of new clock pulses, the clock generator having
- an input port to receive input clock pulses,
- an output port to deliver the new clock pulses to a target circuit that uses the new clock pulses to determine at least a start time or a stop time of a signal generated by the target circuit, and
- a pulse delay to govern a width of the new clock pulses, the pulse delay including a circuit to adjust the width to compensate for variations in process, voltage and temperature.
