Abstract
The present invention provides a circuit and method using a floating PMOS transistor connected in series between the transistors of an input invertor. The floating PMOS transistor may be used to control the amount of current through the transistors. The gate of the floating PMOS transistor may be connected through a reference line to a duplicate of the input inverter stage. The duplicate stage is generally located in a reference block and fed with a stabilized reference voltage. Each couple (formed by the buffers input stage and the duplicate stage) functions as a differential comparator, which checks the input voltage against the reference voltage and rejects the power supply voltage variations which are perceived as a common-mode noise signal. The supply current is fixed by the reference voltage which reduces power consumption at high input voltages and high supply voltages.
