Abstract
An amplifier circuit (30) has the capability for driving a large number of loads while still maintaining the desirable gain response. The amplifier circuit (30) includes two push-pull amplifier circuits (31 and 41). A first push-pull amplifier circuit (31) has a pair of bipolar transistors (33 and 34) connected in a cascode circuit configuration and a second pair of bipolar transistors (35 and 36) connected in a cascode circuit configuration. In addition, the second push-pull amplifier circuit (41) has a first pair of bipolar transistors (43 and 44) connected in a cascode circuit configuration and a second pair of bipolar transistors (45 and 46) connected in a cascode circuit configuration. The channel distortion and gain response of the amplifier circuit (30) are significantly improved by the push-pull amplifier circuits (31 and 41).
