ABSTRACT:
A high gain transistor amplifier with internal balancing bias having a common mode input range which includes a supply rail includes a differential to single-ended converting input stage including at least one pair of transistors, each transistor having first and second current terminals and a control terminal; input means for providing an input signal to the first current terminals of the transistors; a voltage amplifier stage for providing an amplified output of the input signal, the voltage amplifier stage including at least one transistor having a control terminal; and a biasing circuit responsive to the voltage amplifier stage for maintaining balanced currents between the control terminal of the voltage amplifier stage and the control terminals of the differential to single-ended converting input stage, the biasing circuit being connected to the second current terminals of each transistor pair and the voltage amplifier stage being connected to one of the second current terminals so that the first terminal may be driven in a common mode potential range which includes a supply rail.
