Title:
温度安定化発振器及び同発振器を含む近接スイッチ
Document Type and Number:
Japanese Patent JP4620188
Kind Code:
B2
Abstract:
The oscillator has an oscillation loop (L,C,R) and an amplifier circuit connected as virtually negative resistance. A current source is connected in series with the oscillation loop to determine a signal for the resistance of the oscillation circuit coil. A control circuit is provided which, by using the signal, makes the virtually negative resistance essentially inversely proportional to the resistance of the oscillation circuit coil. The control circuit may be a DC source, a pulsing DC source or a low frequency AC source. The control circuit may amplify the output voltage of the amplifier circuit with a voltage which is a linear function of the derived signal.
