Oscillator having capacitor charged and discharged by current mirror circuits |
摘要 |
An oscillator circuit adapted for use as a voltage controlled oscillator in which all of the transistors of the oscillator circuit are operated in non-saturated regions so that the minority carrier accumulation time does not affect the maximum operating frequency of the circuit. First and second current mirror circuits are coupled to opposed outputs of a differential amplifier circuit and are coupled to charge and discharge a capacitor with constant current in response to the states of the differential amplifier circuit. The differential amplifier circuit is provided with a hysteresis characteristic.
