Abstract
A new model allows prediction of bipolar junction transistor (BJT) transient, DC or small-signal self-heating based on device geometry. The models are implemented in SPICE using multiple-pole RC models for thermal impedance. Polynomials are used to predict the RC circuit values. Circuit simulations demonstrate the conditions that make some circuits sensitive to self-heating.Keywords
