Title: Voltage controlled oscillator circuit
Inventor: YAMAGISHI MIKIO
IPC: H03B5/32
Filed: 1992-04-23
Abstract: PURPOSE:To expand the variable range in the oscillating frequency by providing a means controlling the oscillation intensity of an oscillation circuit in response to a control input used to control the oscillating frequency to the oscillation circuit so as to prevent the oscillation stop when the control input is too high. CONSTITUTION:An oscillation circuit 10 consists of a couple of transistors(TRs) 12, 13 of differential connection and a current source TR 14 connecting to a common emitter of a couple of the TRs 12, 13, and a means to change the oscillation intensity controls a current flowing to the current source TR 14. Moreover, a reactance circuit 11 is provided with a current mirror circuit whose output current varies with a control input and the means changing the oscillation intensity includes an input TR and a TR of current mirror connection being components of a current mirror circuit. Since the oscillation intensity of the oscillation circuit 10 is increased in response to the control input when the impedance of a positive negative reactance circuit 11 is reduced, the oscillation stop is prevented even when a control variable is increased.

IPC: H03G3/30
Filed: 1990-04-20
Abstract: PURPOSE:To resolve the unstable operation for a low control power level and to extend the power control range by constituting a circuit so that the gain of an amplifier in the output stage in a power amplifier is varied by the feedback voltage and changing the gain of an amplifier in the preceding stage of the amplifier in the output stage by a control signal. CONSTITUTION:The circuit is so constituted that the gain of an amplifier 33 in the output stage in a power amplifier 30 is varied by the feedback voltage, and gains of amplifiers 31 and 32 in the preceding stage of this amplifier 33 are changed by the control signal. Consequently, gains of amplifiers 31 and 32 in the preceding stage in the power amplifier 30 are reduced by a gain varying means in accordance with the control signal when the output power of the power amplifier 30 is reduced based on this control signal. Thus, the power level to the amplifier 33 in the output stage is reduced to stably operated this amplifier 33, and the output power is reduced, and the output power control range in the whole of the power amplifier 30 in extended.
