Abstract
A circuit that includes a self-biased differential amplifier a level restore circuit. The output of the differential amplifier is coupled to the source pins of a p type transistor and an n type transistor. The output of the differential amplifier is further coupled to a first inverter circuit that provides feedback to the gates of the p and n type transistors. The first inverter also further amplifies the output voltage of the differential amplifier. When the differential amplifier outputs a high voltage, the p transistor attempts to drain the output and pull the output voltage down. When the differential amplifier begins switching from a high voltage to a low voltage, the p transistor accelerates the voltage swing and decreases the propagation delay of the buffer circuit. Likewise, when the differential amplifier swings from a low voltage to a high voltage, the n type transistor reduces the propagation delay of the voltage swing.
