Thomas D Fletcher, Edward A Burton, Benny T Ma: CMOS driver circuit having reduced switching noise. North American Philips Corp Signetics Div, David Schreiber, August 31, 1993: US05241221 (32 worldwide citation)

In a driver circuit, high- and low-impedance drive means (26 and 28 respectively) operate in parallel to effect a desired output transition. Adaptive control means 32 respond to a threshold value of the output signal (VO) and turn off the low-impedance drive means in the course of the output transit ...

Charles E Dike: Metastable-immune flip-flop arrangement. North American Philips Corp Signetics Div, T Briody, A Tamoshunas, R Meetin, October 16, 1990: US04963772 (17 worldwide citation)

A D-type flip-flop arrangement includes first and second latches .Circuitry interposed between the latches blocks any metastable condition that may occur in the first latch from propagating into the second latch. Additionally, the arrangement minimizes the likelihood that the first latch will enter ...

Ronald L Cline: Electronic circuit with capacitively enhanced switching. North American Philips Corp Signetics Div, A Tamoshunas, J Haken, R Meetin, February 11, 1992: US05087837 (1 worldwide citation)

A circuit formed with an input stage (20) and an output stage (22 or 28) uses capacitively enhanced switching to improve switching speed without significantly raising steady-state current utilization. The output stage contains a pair of amplifiers (A1and A2) that respond to complementary signals (V. ...
