Title: Logic gate
Inventor: SUKOTSUTO JIEI GURIFUISU
IPC: H03K19/096
Filed: 1989-04-27
Abstract: PURPOSE: To execute a high-speed logic function by connecting a sense amplifier to a sense rail and a reference rail, detecting a voltage of both rails and generating a prescribed output, when a voltage on one rail exceeds the voltage on the other rail. CONSTITUTION: An OR gate has a drive rail 310, a sense rail 315 and a reference rail 320. Then, when all of the inputs I1 -In are low, the voltage on the sense rail 315 becomes higher more quickly than the voltage on the reference rail 320, and this voltage difference is detected by a sense amplifier 366. A prescribed signal expressing the inputs are not high is outputted. Further, when the more than one input are high, the sense rail 315 is turned to a ground potential, and afterwards the sense amplifier 366 detects the voltage on the reference rail 320 exceeds the voltage on the sense rail 315, and a signal expressing more than one input are high is outputted. Thus, the logic OR function can be executed at a high speed.
