High-speed and low-voltage TTL AND-NOT gate to turn on amplification-state
Guo Long-di · Journal of Circuits and Systems · 2009
After analyzing the difficulty to realize a high-speed and low-voltage TTL gate by tradition idea,a TTL circuits to turn on amplification-state by the using of emitter follower clamping-and-feedback circuit is presented and the high-speed and low-voltage TTL AND-NOT gate of delay-time tpd1ns is designed mainly in this paper.Secondly,a circuit analysis and parameter estimate are made out for reference to improve at high-speed and low-voltage.The theory and circuits are verified by computer simulation.
