Abstract :
This paper presents the simulation results of the gate-controlled diode, working in the analog regime. The aim of the paper is to find the device macromodel that provides an optimum linearity of the junction voltage versus the gate voltage, at a given current. The lateral pn junction is simulated in the breakdown regime and the gate voltage biases the MOS capacitor in deep depletion. Finally, linearity under 1% was accomplished, being in agreement with the theory. An equivalent circuit was developed according to these simulations in order to be implemented in Spice like programs.
