Title: Transistor amplifier
Inventor: NAGASAWA TOSHIAKI
IPC: H03F1/34
Filed: 1979-01-24
Abstract: PURPOSE:To ensure to prevent the rapid increase in the signal level in the circuit, by giving forward current to the base of the predrive transistor when the clipping of the output waveform is detected. CONSTITUTION:When the base potential of the drive transistor Q10 is excited toward negative direction, the diode D2 is conductive immediately before the base potential of Q10 reaches the negative power supply voltage given by the negative power supply E2, and the base current is fed to the base of Q15 from the DC voltage source E6. Thus, Q15 is conductive so that the base potential of the predrive Q7 can be lowered via the resistor R17. At this moment, the base potential of Q7 is kept at an equilibrium value to suppress the rapid increase in the signal in the circuit at output clipping. On the other hand, when the base potential of Q10 is excited forward, the diode D2 is back-biased and inoperative and Q15 is in non- conduction to substantially cut off the circuit in the broken lines, allowing to avoid any effect to the essential operation of the amplifier.
