Abstract:
A configurable delay cell for an integrated circuit includes a CMOS inverter and first through fourth transistors. A drain of the third transistor is connected to a drain of the fourth transistor for generating an output signal. A connection between an output terminal of the CMOS inverter and a source of the first transistor, a connection between the output terminal of the CMOS inverter and a drain of the second transistor, and a connection between the source of the first transistor and the drain of the second transistor are configurable, using an electronic design automation (EDA) tool, for achieving first, second, third, fourth, and fifth delay values. The resulting delay value can be programmed by making changes only in one or more of the metal layers of the integrated circuit.
