Zero-temperature-coefficient biasing point of a fully-depleted SOI MOSFET

The gate characteristics (I-D-V-GS) of fully depleted, lightly doped, enhanced SOI n-MOSFET are simulated over a wide range of operating temperature (300-600 K) by using the SILVACO TCAD tools. Simulation results show that there exists a biasing point where the drain current and the transconductance arc temperature independent. Such a point is known as the zero-temperature coefficient (ZTC) bias point. The drain-current ZTC points arc identified in both the linear and saturation regions. The transconductance ZTC exists only in the saturation region. (C) 2003 Wiley Periodicals, Inc.
