发明名称 Non-overlapping clock generator circuit and method therefor
摘要 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. Once the clock signal has propagated through the active delay line, the feedback signal changes and allows NOR gates of the remaining delay line to simultaneously provide a clock signal and a delayed clock signal.
