Abstract
A system and method for compensating for process, voltage, and temperature variations in a circuit is provided. A system includes an inverter having an input port, and an output port, and is configured to (i) receive an input signal, (ii) delay the received input signal, and (iii) provide the delayed signal to the inverter output port. The system also includes a logic device including at least two input ports and an output port. A first of the at least two input ports is configured to receive the delayed signal. Finally, the system includes a charge storing device having a first end coupled, at least indirectly, to a second of the at least two input ports and a second end coupled to a logic device common node. The charge storing device is configured to (i) receive the input signal and (ii) sense a rate of change in voltage of the received input signal, the sensed voltage being representative of a corresponding current. The logic device output port is configured to output an output signal responsive to the delayed signal and the corresponding current.
