Publication number: 20090091399Abstract: Systems and methods which provide an oscillator circuit outputting non-overlapping trigger signals throughout a range of operating voltages using a reset-set (RS) flip-flop type circuit configuration are shown. Embodiments utilize output driver buffers internal to the RS flip-flop circuit configuration to provide oscillator feedback delay. Feedback control circuitry may be implemented to ensure that the delay associated with any one driver buffer does not solely provide the feedback delay.
