ABSTRACT:
An output stage is disclosed wherein class AB bias is employed. The stage is quiescently biased by means of current mirrors so that the bias is controlled mainly by ratioed geometric elements. The output transistors are biased by means of unity gain common gate drivers that provide the desired level shifting. The output voltage can be swung from from close to the rail potential of the source of the n channel output transistor to close to the rail potential of the source of the p channel transistor. The circuit can drive relatively large load currents and can be fabricated using either CMOS or conventional bipolar integrated circuits.
