In this work, three different logic cell configurations, two with and one without a source-follower are employed: These logic cells are arranged in 5- and 11-stage ring oscillator (RO) circuits. The circuits are then fabricated with nominal gatelengt

The ideal semiconductor target for EBS devices is most closely approximated by the Schottky barrier junction, with Al having the highest figure of merit. Accordingly, large area (1·27 mm 2 ), high-field Al n Si Schottky barrier junctions surroun

An idealized device model is employed to determine the optimum material parameters for low-high-low (LHL) GaAs IMPATT's. Experimental efficiencies of 15-GHz devices indicate the model is of considerable utility for LHL GaAs IMPATT design.

A novel GaAs MESFET logic gate is described. The gate uses depletion mode FET's and is a static one. It is about 30% faster and consumes about 30% of the power of the BFL gate. Ring oscillator circuits have been fabricated using one embodiment of the

Circuit parasitic capacitances for GaAs ring oscillators (RO's) were calculated and used for SPICE2 circuit simulation. The simulated delays agreed with the measured data to within ∼10 percent. The results indicate that the effect of the circuit pa
