In this communication a circuit for the detection of the Threshold Voltage Vth of MOS devices is presented. The basic scheme here proposed is implemented in BiCMOS technology but can also be applied in any standard CMOS process. The deviation of the 'detected' Vth (VTHdet) from the 'actual' (or extrapolated) one (VTHext) is analytically estimated keeping into account in particular the effects due to the channel length modulation and the mobility modulation.

Abstract
In this communication a circuit for the detection of the Threshold Voltage Vth of MOS devices is presented. The basic scheme here proposed is implemented in BiCMOS technology but can also be applied in any standard CMOS process. The deviation of the 'detected' Vth (VTHdet) from the 'actual' (or extrapolated) one (VTHext) is analytically estimated keeping into account in particular the effects due to the channel length modulation and the mobility modulation.
