A method of accurately simulating the frequency response of a millimeter-wave SiGe amplifier is presented. Electromagnetic (EM) simulation is applied to the cascode sub-circuit in preference to parasitic extraction resulting in improved agreement between simulated and measured performance. Including resistors and capacitors in the EM simulation allows coupling and resonance effects to be captured which improves the simulation accuracy. Close agreement is obtained between the measured and simulated results for a 30 to 40 GHz two-stage transformer coupled amplifier fabricated using IHP's 0.25μm SG25H1 process.
