A diode is connected to form part of a frequency establishing network of an oscillator and is biased to operate in the region of high dynamic resistance of its voltampere characteristic curve. Because the diode is biased in its forward direction, it can be used in low voltage circuits. A capacitor isolates the oscillator from the biasing current, and the high dynamic resistance of the diode reduces the conductive load on the oscillator.
