Abstract
A reference pulse generator comprises a quartz crystal oscillator, a frequency divider connected to the oscillator for frequency dividing the oscillator output, and a constant current generator connected in series both with the oscillator and the frequency divider to control the current applied to the oscillator from a power source. The constant current generator comprises a current limiting element, such as a MOSFET, which is controlled by a reference voltage produced by a reference voltage generator.
