Title: Power calculation when a high-frequency sinusoidal voltage source is applied Post by Peng_Li on Oct 4^{th}, 2019, 8:20pm Hi, In my recent work, I need to calculate the electrical power consumed by a conductor (using Verilog-A). As we know, the impedance of a conductor varies with the frequency of the electrical excitation applied. For example, its dc resistance is assumed to be R_{dc}, and the resistance at 20 GHz is assumed to be R_{ac} (because of skin effect). The electrical excitation is a sinusoidal voltage source, which is expressed as V=V_{0}+V_{a}*sin(2*pi*freq*t) where V_{0} is the dc component; V_{a} is the amplitude of the ac component; freq is the frequency; t is the time. My question is, in the following, which is the correct way to calculate the electrical power consumption of the conductor? (1) Power consumption on R_{ac} with both dc and ac voltage component applied (2) The summation of dc power consumption on R_{dc} and ac power consumption on R_{ac} Any help would be greatly appreciated, thank you. |

Did you try running a simulation on existing models for a conductor in Spectre or any other simulator to cross verify 1 and 2? |
