ABSTRACT:
A self-adjusting precharge level circuit for coupling to an N-channel precharged bus line. The precharge circuit comprises first, second, and third N-channel transistors and first and second inverters. The first transistor couples the bus line to a positive power supply voltage terminal during a precharge period when the voltage on the bus line falls below the positive power supply voltage minus an N-channel MOS transistor threshold. The second and third transistors together couple the bus line to a second power supply voltage terminal during the precharge period when the voltage level of the bus line rises above positive power supply voltage minus the N-channel MOS therehold, after the voltage level is sensed by the first and second inverters. Sensing and adjusting the voltage in this manner allows the circuit to maintain an N-channel precharge level on a bus which has circuits driving CMOS levels coupled to it, while dampening the voltage response and suppressing oscillation.
