Abstract: A non-inverting, inverting, delayed non-inverting, and delayed inverting non-overlapping clock signal is provided by a non-overlapping clock generator circuit (41, 61). The non-overlapping clock generator circuit (41, 61) increases time for circuit operation by minimizing delays between non-overlapping clock signals and simultaneously transitioning rising edges of clock signals. A non-overlapping clock generation circuit (41) comprises six NOR gates (43-48) and an inverter (42). Three NOR gates form a first delay line (43-45) and the remaining three NOR gates form a second delay line (46-48). The inverter (42) provides an inverted clock signal to the second delay line. A clock signal propagates through one delay line while the other delay line is non-responsive due to a feedback signal from the active delay line.
