  • Wideband linear Darlington cascode amplifier
    Patent number: 4706038
    Abstract: This disclosure relates to a multi-channel power amplifier utilizing Darlington pairs as the inputs of a cascode amplifier. The Darlington pair inputs may implement an added grounded resistor to the emitter of the pre-driver transistor in each Darlington pair. The added resistance allows for individual adjustment of the dc current in the pre-driver transistor of each Darlington pair, as well as an additional discharge path for the charges stored on the base of the driver transistor in each pair during a decreasing current state.
