1. A skewed buffer rising logic device for rapidly propagating a rising edge of an output signal comprising:

  • a fast inverter falling having a large n/p channel width ratio for receiving a rising edge of an input signal and rapidly propagating a falling edge of an intermediate signal in response thereto;

    a fast inverter rising having a large p/n channel width ratio and in series with said fast inverter falling for receiving said rapidly propagated falling edge of said intermediate signal and rapidly propagated rising edge of said output signal;

    a reset network coupled to said fast inverter falling and said fast inverter rising for resetting output signals of said fast inverter falling and said fast inverter rising after said rising edge of said output signal has been rapidly propagated; and

    a feedback delay circuit operably coupled between an output of said fast inverter rising and an input of said reset network for propagating said output signal to said reset network.
