Analytical model of GaAs MESFET output conductance with frequency and temperature dependent parameters

Creator:

Lam, Steven C. F.

Abstract:

The output characteristics of a conventional GaAs depletion-mode MESFET device have been investigated. One of the important parameters of the small-signal GaAs MESFET model, g[subscript ds] (output conductance), is shown to be frequency and temperature dependent. Variations in g[subscript ds] are a serious problem in many analog and digital circuits...

Modeling of subthreshold current of GaAs MESFET and the design of voltage reference circuit

Creator:

Or, Pee-Keong

Abstract:

The characteristic of the subthreshold current in a GaAs MESFET exhibits a negative exponential function with Vgs. After studying the behavior of this current in this region over a range of temperature and drain bias voltages, a subthreshold current model was developed. The model was implemented in a circuit simulation...
