Abstract
The square-wave output of a comparator is coupled back to the input of an RC controlled integrator including an operational amplifier and an inverter circuit with an output signal maintained at a predetermined level. The RC network sets the pulse repetition rate of the square wave. The inverter and integrator outputs are connected to separate inputs of the comparator. A gating circuit couples a data source to the operational amplifier. In particular, the gating circuit couples an additional square-wave current to the integrator via a resistor. The square-wave current may be in phase and raise the pulse repetition rate of the resulting square wave or out of phase and lower the pulse repetition rate.
