Measuring Power Consumption in GDI based circuits

JagdishP

Hello,

I am trying to measure total power consumption of my design based on GDI (Gate Diffusion Input) technique.

I want to know that is the procedure for measuring power is same for GDI like, multiplication of Vdd with current supplied by vtg source using calculator.

Please help if this is not the right way of measuring power perticularly for GDI based design  

  • I'm not really familiar with this Gate Diffusion Input technique, but from a quick scan of the literature (this seems quite a useful paper), I can't see why you wouldn't measure the power consumption in the same way - the multiplication of the supply voltage with the current through the supply. Of course, you may need to take into account any power supplied through the signal inputs too - the power needed to drive the input. But that's no different from any other kind of circuit.

  • Sir can i get to know the process parameter vaules for 180nm CMOS technology.

    value of Kn' and Kp' of nmos n pmos respectively.

    or where can i find this values.

    I build an simple Cmos inverter and in result brower under DC-INFO-DC i got to know betta(B) vaule of MOS.

    but everytime I run the simulation I get different vaules.
