ABSTRACT:
A network for initiating oscillations of a low power oscillator circuit at low operating voltages. The oscillator circuit includes an inverter with a quartz crystal connected between its input and output and with impedance means connected in series with the main conduction path of the inverter to reduce its power dissipation. The initiation network includes a switching means which is connected in parallel with the impedance means and which is responsive to the application of an operating potential to the oscillator circuit for momentarily providing a low impedance conduction path in parallel with the impedance means when an operating potential is applied to the circuit.
