  • Base drive regulator
    Patent number: 4055794
    Abstract: A base drive regulator for regulating the base drive voltage of the output transistor of a switching amplifier. The inputs of a comparator are separately connected to a reference voltage of either an independent source or the base of the output transistor and to a resistor network connected between the collector and emitter of the transistor. The output from the comparator is utilized to indirectly control the conductivity of the output transistor to maintain the output transistor just at saturation.
