Abstract

PURPOSE:To make stable oscillation frequency by reducing the variation in gate bias given to PUT. CONSTITUTION:The transistor 11 is placed between the output terminal of the Zener diode 2 and the voltage dividing resistor R1, the collector is connected to the output terminal of the Zener diode 2 and the emitter is connected to the voltage dividing resistor R1, and bias is given to the base from the DC power supply VCC via the resistor R5. When the power supply voltage VCC is decreased, the voltage between the collector and emitter of transistor 11 is increased to compensate the lowering in the oscillation frequency accompanied with the decrease in the power supply voltage VZ.
