ABSTRACT:
A multi-level signal generating circuit is disclosed which comprises: a first CMOS inverter for inverting an input signal to produce a first output signal having high and low voltage levels; a second CMOS inverter for inverting the input signal to produce a second output signal having high and low voltage levels; at least one of the high and low voltage levels of the second output signals being different from said high and low voltage of said first output signal; and switching circuit operative to drive selectively said first CMOS inverter or said second CMOS inverter in response to a level of a control signal.
