ABSTRACT:
A CMOS inverter circuit is provided which includes a compensation circuit which modifies the inverter threshold depending on changes in supply voltage and/or temperature. The inverter includes a standard CMOS inverter, current boosting circuitry and a reference signal generator. The input of the inverter is coupled to the current boosting circuitry. A reference signal is also coupled to the current boosting circuitry in order to change the effective PMOS to NMOS ratio of the inverter to control the input threshold over a range of supply voltages and/or temperatures. The reference signal generator generates a reference signal which is dependent upon changes in supply voltage and which can be controlled over a range of temperatures.
