ABSTRACT:
A voltage controlled oscillator whose frequency is a function of an input voltage having a first and a second pair of switching devices coupled respectively to first and second terminals of a capacitor. The oscillator has a first leg coupled from the first capacitor terminal through first inverter means, a first NOR device and third inverter means back to the first pair of switching devices and the first capacitor terminal. The second leg is coupled from the second capacitor terminal through second inverter means, a second NOR device, fourth inverter means back to the second pair of switching devices and the second capacitor terminal. The first and second NOR devices are directly cross-connected. The first and second legs each have the same number of propagation delays and during state transition, both terminals of the capacitor are coupled to the reference potential for a brief instant of time.
