<p>The cascomp amplifier is modified to provide a dynamic biasing circuit which varies the bias point of the cascomp amplifier in proportion to the change in the true bias point of the main channel pair (Q,, Q<Sub>2</Sub>) to allow full thermal V<Sub>b</Sub>e error correction for overdrive conditions and for common-mode signals. A buffer amplifier (Qs, Q<Sub>6</Sub>) senses the average voltage (V<Sub>E</Sub>) of the main channel input transistor emitters and generates a voltage proportional to this average which is added to the biasing network for the cascomp amplifier common-base amplifier transistors (Q<Sub>3</Sub>, Q<Sub>4</Sub>).</p> |
