Title: Voltage control oscillator
Inventor: HIKITA JIYUNICHI
IPC: H03K3/0231
Filed: 1983-04-12
Abstract: PURPOSE:To prevent the variance of the oscillation frequency due to a power source voltage to reduce a driving voltage by giving the output of a current inverting circuit as a driving input to a transistor TR which gives a charging current to a TR and a capacitor which switch an upper limit comparison voltage or a lower limit comparison voltage. CONSTITUTION:PNP TRs 62 and 64 are inserted as loads to the collector side of TRs 2 and 4 constituting a voltage comparator, and the current inverted output obtained by the current inverting circuit consisting of these TRs 62 and 64 is given to bases of TRs 30 and 52 to drive TRs 30 and 52. That is, the gain of a differential amplifier consisting of TRs 2 and 4 is twice as high as that of a conventional circuit by adding TRs 62 and 64. Therefore, the influence of the variance of a power source voltage Vcc is reduced, and the variance of the oscillation frequency due to the power source voltage is reduced.
