FAST SWITCHING INPUT BUFFER

摘要

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.
