I wanna use only one power supply of 1.2V. My question is, (1) Can I use 1.2 V as Vdd power supply in 180nm Process or I can use only 1.8V as Vdd. (2) Is it true that 1.8 V is maximum available power supply in 180nm process and I can use a power supply less than 1.8V.

Click to expand... Depends on available process options. Without additional voltage (i.e. oxide thickness) options, 1.8V usually is the max. power supply voltage for this process.
