Abstract
An improved linear amplifier circuit includes current mirror circuits that are cross connected in the collector circuits of input transistors for supplying proportional current to circuit nodes from which signal is derived for controlling the output stages. The states for supplying boost current to the circuit nodes are stabilized in quiescent condition to avoid delays commonly associated with the turning on of a non-conducting stage.
