Title: Phase synchronizing oscillator circuit
Inventor: FUNAI MIKIO
IPC: H03L7/22
Filed: 1990-03-30
Abstract: PURPOSE:To obtain the phase synchronizing oscillator circuit which can be realized extending over a wide frequency range by constituting it so that an output frequency range of a desired oscillator is brought to phase synchronization in plural multiple degrees extending over an output frequency range or above of a voltage control oscilla tor. CONSTITUTION:An output frequency fVCO of a voltage control oscillator 1 is brought to RM multiplication through a multiplier 7, and mixed 2a with an oscillation frequency fOSC of a desired oscillator, for instance, a YTO 8. In this state, a part of an output of the oscillator 1 is brought to frequency division by an NM frequency divider 12, and in this case, brought to phase comparison 5b with a reference signal of 100kHz and brought to feedback to the oscillator 1. Subsequently, RM executes multiplication, for instance, within a range of 20-90. Next, a single brought to phase comparison 5a of an output of an LPF 10 and fIF of an IF frequency is brought to feedback to the oscillator 8. In this case, this circuit is constituted so that an output frequency range of the oscillator 8 is brought to phase synchronization in a multiple degree extending over an output frequency range or above of the oscillator 1. Accordingly, in a hardware constitution of an fVCO generating loop, it is possible to eliminate the need of a mixer, and a phase synchronizing oscillator which can be realized in a wide frequency range is obtained.

Title: Audio amplifier
Inventor: NOGUCHI NAOKI
IPC: H03F1/00
Filed: 1984-04-27
Abstract: PURPOSE:To operate the bias circuit of an amplifier body after the uninverted (NF) of the amplifier body terminal becomes stable, speed up its output and smooth its rise, and reduce pop noises during power-on operation by stopping the operation of the bias circuit and charging capacitor connected to the NF terminal of the amplifier main body. CONSTITUTION:When the power source is turned on, the base voltage of a transistor (TR) 26 rises slowly with the time constant determined by a resistance 24 and a capacitor 25. Then, a TR38 is turned on by current mirror circuits 32 and 37, and a TR38 absorbs a current from the constant current source 1 of the amplifier body 50 to turn off TRs 4 and 5. Thus, the TR5 turns off and the NF terminal 20 is charged, so that the level at an output terminal 17 goes up to ''L''. Then, the TR5 turns on after the NF terminal 20 becomes stable (1VBE), so the output rises smoothly.
