To extend the lower bound of power supply to ultra-low voltages (0.6 V and below), we propose a Dynamic-Threshold Voltage MOSFET (DTMOS) built on Silicon-On-Insulator (SOI). The threshold voltage of DTMOS drops as the gate voltage is raised, resulting in a much higher current drive than standard MOSFET at low power supply voltages. On the other hand, Vt is high at Vgs = 0, therefore the leakage current is low. We provide experimental results and 2-D device and mixed-mode simulations to analyze DTMOS and compare its performance with a standard MOSFET. These results verify excellent DC inverter characteristics down to Vdd = 0.2 V, and good ring oscillator performance down to 0.3 V for DTMOS.
