Abstract
In an oscillator circuit, a high gain, high power driver is placed in parallel with a standard low gain, low power driver for driving the oscillator output. A control signal is derived from the output of the oscillator circuit and fed back to control the high gain driver. After the circuit output has achieved stable oscillations for a predetermined time period, the high gain driver is turned off. Employment of the high gain driver ensures high start-up ability. The overall power consumption remains low since the high gain driver is turned off after stable oscillations have been achieved.
