  • Voltage control circuit
    Patent number: 5105145
    Abstract: To stop high-voltage breakdown of a transistor (T1) in an amplifier circuit, a selectively conducting means, e.g. a diode (D), provides a low resistance path in response to a switching or control transistor (T8). Upon initiation of breakdown, the diode (D) conducts to block transistor (T1) and prevent damage thereto. The transistor (T1) is part of a multi-stage output amplifier (12) connected to an input differential amplifier (11). The output voltage is back to a transistor of the input amplifier (T7). The diode (D) may be replaced by a transistor (T, FIG. 2).
