Fixing the Curtice FET Model

Method used to prevent convergence difficulties in the Curtice model when parameter extraction is imperfect
Technical Feature Fixing the Curtice FET Model Convergence difficulties are common in nonlinear analyses of circuits using a Curtice model. The problem is not the model itself, but the limitations of the parameters describing the gate I/V characteristic. In this article, we show why that failure occurs, and how...

Simulating Multi-finger HBTS

Introduction to a new model of multi-finger heterojunction bipolar transistors used to analyze and predict current collapse, bias dependence and output power
Technical Feature Simulating Multi-finger Power HBTs A new model of multi-finger heterojunction bipolar transistors (HBT) is presented to analyze and predict current collapse, bias dependence and output power. The simulation of multi-finger HBTs has proven to be very challenging in both computer-aided design and electromagnetic (EM) simulation. However, by...
