Abstract
A circuit for producing a reliable duty cycle for a low power oscillator. The circuit produces a square wave signal based on the differences between the oscillating output signal driven by a piezoelectric crystal and a phase shifted output signal. This circuit provides a quick start for a clock signal, generates a reliable fifty percent duty cycle and is better protected from common mode noise. This circuit can also be configured to be programmable to provide for an adjustable duty cycle.
