ABSTRACT:
An inverting amplifier having linear output characteristics is disclosed which includes additional n-channel and p-channel transistors coupled to a classic CMOS inverter circuit. The linear transfer characteristic is achieved with nearly full dynamic V.sub.cc range. The invented amplifier yields a linear transfer characteristic by controlling the dimension ratios between each of the transistors. The wide dynamic range, wide bandwidth and low output impedance make the circuit well-suited for use as an output stage of a CMOS operational amplifier.
