Abstract
Integrated circuits described herein implement an x-input logic gate. The integrated circuit includes a plurality of Schottky diodes that includes x Schottky diodes and a plurality of source-follower transistors that includes x source-follower transistors. Each respective source-follower transistor of the plurality of source-follower transistors includes a respective gate node that is coupled to a respective Schottky diode. A first source-follower transistor of the plurality of source-follower transistors is connected serially to a second source-follower transistor of the plurality of source-follower transistors.
