Process-voltage-temperature tolerant replica feedback pulse generator circuit for pulsed latch

Abstract

Embodiments herein relate to a pulse generator which provides first and second clock pulses to one or more pulsed latches, where the pulse generator replicates a delay of the pulsed latches in providing the first and second clock pulses. The pulse generator can include a replica of latch components in the pulsed latches such as a tri-state inverter, a transmission gate and inverters, where an output of the tri-state inverter is coupled to the transmission gate and to an input of the inverter, and an output of the inverter is coupled to an input of the tri-state inverter. The tri-state inverter can be a modified tri-state inverter with an output forced to “1” when a clock signal is “0.” In one approach, the latch components of the pulse generator are to write a logic 1 when a clock signal goes high.
