This work investigates the possibility to tune the zero-temperature-coefficient (ZTC) points in partially depleted (PD) SOI nMOSFET technology by controlling the body-source forward bias (V/sub BS/). Measured transconductance and drain current in the saturation region at temperatures between 25 and 200 degrees C were observed for various body-source forward bias conditions. It is found that the variation of threshold voltage (V/sub TH/) with body bias has an influence on ZTC points. The measurement results show wide voltage-range of gate-voltage giving either the transconductance ZTC point (V/sub GS/,/sub ZTC9m/) or the drain-current ZTC point (V/sub GS/,/sub ZTC1DS/) opening important opportunities in RF circuits design for nigh temperature applications.
