Scalable Vector Graphics SVG 1.0 Specification

An MOS oscillator is disclosed in which a pair of delay networks are provided, each having two inputs and two outputs, each network having the operating characteristic that a change in one of its inputs in a given sense produces a change in its outputs in a relatively short time and a change in the other of its inputs in that given sense produces a change in its outputs in a relatively long time, the two networks having their inputs and outputs cross-connected. The networks may be formed of MOS devices, all of them on a single substrate. From such a network two sets of outputs are obtained, one set being in the form of complementary pulses and the other set being in the form of complementary square waves. The frequency of operation of the oscillator can be controlled by varying the voltage applied to MOS devices in the circuit which function as resistors, thereby modifying the time constant of capacitor-charging circuits in which those resistors are present.
