ABSTRACT:
An output driver circuit with improved output stage clamping comprises an input stage, an output stage, and a clamping circuit. The input stage amplifies a difference between an input signal and a reference signal to provide first and second output signals for driving gates of first and second transistors which together form the output stage. The first and second transistors are serially coupled between first and second power supply voltage terminals and provide an output signal. The clamping circuit clamps the first signal at a predetermined gate-to-source voltage below the first power supply voltage, and clamps the second signal at a predetermined gate-to-source voltage above the second power supply voltage terminal. The clamp voltages are maintained by matching current densities and bias conditions between the first and second transistors, and corresponding transistors in the clamping circuit.
