ABSTRACT:
A wide bandwidth, phase-stable amplifier circuit (10) and method is provided. Amplifier circuit (10) comprises amplifier cells (12a) and (12b) and a low impedance summing circuit (14). Each of amplifier cells (12a) and (12b) are biased at a predetermined bias current lower than a typical amplifier cell. The output of amplifier cells (12a) and (12b) are coupled to amplifier circuit (14) having transistors (30) and (32) coupled in a cascode configuration. By using the low bias current in amplifier cells (12a) and (12b) and the low impedance summing circuit (14), amplifier circuit (10) provides a wide bandwidth, phase-stable amplifier circuit.
