Abstract :
This paper reports a new Dynamic Threshold Voltage MOS (DT-MOS) transistor using foundry 90-nm CMOS process. Adopting the sub-circuit of the source follower, the proposed device could be operated in the voltage over 0.7 V. Measurement results demonstrate the 33% improvement of current driving capability and 20% improvement of transconductance compared to the reference MOS transistor. Moreover, the achieved high transconductance of the proposed transistor enhances the 30% RF performance.
