In this Paper, we present simple physical model of the Capacitance characteristics for GaAs MESFET\`s in wide temperatures. In this model, gate-source and gate-drain capacitances are represented by analytical expressions which are classified into three different regions for bias voltage. This model contained the temperature dependent variable that is the built-in voltage and the depletion width. Using the equations obtained in this work a submicron gate length MESFET has simulated and theoretical result are in good agreement with the experimental measurement.
