Title (EN) FAST SWITCHING INPUT BUFFER
(FR) TAMPON D'ENTREE A COMMUTATION RAPIDE
Abstract: front page image
(EN)An input buffer circuit (300) for a semiconductor device that includes a PMOS transistor (306), an NMOS transistor (308), and a pull-up circuit (314). The pull-up circuit (314) applies a voltage to the bulk region of the PMOS transistor (306) causing a positive body effect which causes the absolute value of the voltage threshold of the PMOS transistor (306) to temporally lower when the input buffer (300) switches. This causes the input buffer (300) to switch faster than conventional input buffers. The input buffer (300) is an inverter, NOR, NAND, or other input buffer.
(FR)L'invention concerne un circuit de tampon d'entrée (300) destiné à un dispositif semi-conducteur comprenant un transistor PMOS (306), un transistor NMOS (308), ainsi qu'un circuit d'incursion haute (314). Celui-ci applique une tension à la région de substrat du transistor PMOS (306) entraînant un effet de corps positif faisant baisser, temporairement, la valeur absolue du seuil de tension du transistor PMOS (306), quand le tampon d'entrée (300) commute, contraignant celui-ci (300) de commuter plus rapidement que les tampons d'entrée classiques. Le tampon d'entrée (300) est un inverseur, un NOR, un NAND ou un autre tampon d'entrée.
