A Circuit Model to Simulate the Logic Operation of Four Terminal Transferred Electron Devices.

Abstract

The operational characteristics of Transferred Electron Logic Devices (TELDs) were summarized and used to devise a circuit model for simulation of basic logic gates. The model consists of an oscillator and a voltage controlled switch. The oscillator is a series of RC circuits that discharge at rates proportional to the TELD domain formation, propagation, and extinction times. The switch is controlled by the oscillator and simulates the internal increase of device resistance due to electron transfer to states of decreased mobility under high field conditions. The model successfully simulated three and four terminal AND and OR gate operations and demonstrated the need for special considerations to be taken when logic operations with TELDs are performed.
