Abstract :
The authors proposes a characteristic current (I_chr) to replace the conventional saturation drive current used to estimate approximate CMOS inverter delay times for deeply scaled devices. The authors also present a new device design method based on I_chr to achieve a higher operation frequency for CMOS inverter circuits. The new method shortens propagation delay time (Tpd) by 15%
