Further referring to FIG 1, the prior art amplifier 2 operates as follows: When there is a difference in the voltages of the inputs 10, 12, a current imbalance is created in the output stage to either the source or sinking transistors so that more current is being sourced or sinked, depending on {HEAD ~ the polarity} of {TAIL ~ the imbalance}
