The effects of self-heating on BJT (bipolar junction transistor) behavior are demonstrated through measurement and simulation. Most affected are the small-signal parameters Y/sub 22/ and Y/sub 12/. A frequency-domain solution to the heat-flow equation which applies to any rectangular emitter geometry is presented. This model, although simple enough for CAD, (computer-aided design) predicts thermal spreading impedance with good accuracy for a wide range of frequencies. The small-signal model has been implemented in SPICE.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
