WebIt is a MOSFET circuit. a) According to this circuit, determine how the ID current is expressed in terms of the VG,μn,Cox,W/L,VDD,RL and RS parameters. We'll think of the transistor as saturated. There should be no parameters in the expression other those that are specified. b) Assuming the transistor is in the triode, repeat step a. WebJan 27, 2013 · You can get the equivalent oxide thickness from the models and calculate Cox. However, a better method would be to use HSPICE to get the Cgate value. Check Chapter 7: MOSFET Capacitance Model in the HSPICE Reference Manual: MOSFET Models for detailed instructions on how to do that.

WebSir, in case of NMOS, we take threshold voltage Vtn ( it is positive) and in case of PMOS, we take threshold voltage Vtp (it is negative). Transistor is said to be OFF if: NMOS OFF: VgsVtp In normal case, we always take NMOS as reference (its opposite is PMOS), so we can take Vtn as Vt.
