Transverse TELDs (Transferred-Electron Logic Devices).
Abstract
The development of a computer-aided analysis for two-dimensional transient simulations of planar GaAs logic devices utilizing the transferred-electron effect is described. The effects of the semi-insulating substrate, diffusion, a Schottky-barrier gate, and the nonlinearity velocity-field relationship are included. The analysis is applied to two- and three-terminal GaAs devices. The switching properties of three-terminal devices are studied both for anode loading and cathode loading. A delay of about 30 ps is obtained with gain for anode loading and for above-threshold-value gate input voltage. Three designs of transverse-domain-spreading (TDS) logic devices useful for an exclusive-OR circuit are analyzed. The shortest output delay is 20 ps and occurs for a TDS device with a control anode and capacitive output electrode. (Author)
