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 .
