摘要： PROBLEM TO BE SOLVED: To solve the problem wherein a transistor for constant current is inserted into a current path so that current value becomes fixed for suppressing frequency variation due to temperature variation, and thus, C/N deteriorates in the conventional oscillation circuit, in which current is shared by a buffer amplifier part and an oscillation part.
SOLUTION: The oscillation circuit is constituted so that the emitters of buffer amplifier transistors 23, 24 in a buffer amplifier part 2 are connected, a current is applied to an oscillation circuit core part 1 of the emitters via a buffer amplifier emitters resistor 50, a current-compensating resistor 52 and a current-compensating MOS transistor 53 are further connected in series with the emitters and connected to the ground. Then, when the current value of a buffer amplifier is varied by the temperature variation, since the potential of the emitters is raised, current for the portion of the rise in the potential by the current-compensating resistor 52 and the current-compensating MOS transistor 53 flows to the ground and is compensated so that the potential of collectors of oscillation transistors 3, 4 become constant.

摘要： PROBLEM TO BE SOLVED: To provide an oscillation circuit for generating an electric signal with a satisfactory CNR (carrier to noise ratio). SOLUTION: In the oscillation circuit E 1 , resonance circuits 21 at the respective oscillation stages 2 to 5 generate electronic signals with oscillation frequencies of f 0 . Since the resonance circuits 21 are connected with the collectors of oscillation transistors 22 and the electric signals in the oscillation frequencies of f 0 are further fed back to their bases, amplitude of the generated electric signals is amplified due to thermal noise of the oscillation transistors 22 and their phases are simultaneously inverted. In addition, since such electric signals are inputted in a plurality of the oscillation transistors 22 on a signal path 8 until they reach an output terminal 7, higher harmonic waves due to their non-linearity are generated. However, the impedance of the respective resonance circuits 21 becomes infinite at the frequency f 0 and substantially becomes zero at a frequency n×f 0 . Thus, the higher harmonic waves are transmitted to a grounding point to the higher harmonic waves without being transmitted to the rear oscillation stages 2 to 5. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide a radio circuit by a direct conversion method, by which mutual interference between sent and received signals and vibration signals is reduced and deterioration in transmission and reception characteristics is suppressed. SOLUTION: A band-pass filter 21 makes only tertiary harmonic waves of a vibration signal from an oscillator 11 to pass through. A divider 31 reduces the frequency of the tertiary harmonic waves to a half and gives a modulator 41 with a local signal of frequency 1.5f. The modulator 41 modulates the local signal by a base-band signal and outputs it. The outputted signal is amplified by an amplifier 51 and is outputted from an antenna 71 via a switch circuit 61. Since the frequency of the transmission signal is 1.5f and that of the vibration signal is f, interference between the transmitted signal and the vibration signal is reduced.

摘要： PROBLEM TO BE SOLVED: To solve a problem of a conventional oscillation circuit that has taken much time until the oscillation circuit reaches a stable operating state from application of power when a feedback gain is low because the feedback gain is constant.
SOLUTION: The oscillation circuit of this invention increases a gain of an amplifier circuit or a feedback circuit at application of power so as to increase the loop gain at application of power and then restores the loop gain to the original loop gain after the oscillation circuit reaches a stable oscillating state. Thus, even the oscillation circuit with a low loop gain can be booted up to the oscillation stable state at high-speed.
