ABSTRACT:
An oscillator circuit and a method of generating an oscillating signal are disclosed. An oscillator comprises a first flip-flop and a second flip-flop coupled with the first flip-flop to provide an oscillating signal. A method of generating an oscillating signal comprises providing the oscillating signal as a first clock input to a first flip flop, inverting the oscillating signal and providing the inverted oscillating signal as a second clock input to a second flip flop, using the output of the first flip flop and the output of the second flip flop to generate a combined output that alternates between a logic low level and a logic high level, and using the combined output to sustain the oscillation of the oscillating signal.
