WebAug 7, 2015 · 7. 0. In BJT hybrid pi small signal model, we have a resistor "ro" between Collector and Emitter. This resistor is to include the change in collector current when there is a small signal voltage change between collector and emitter. (due to early effect) I am finding that all BJT hybrid small signal models keep this "ro" even when there is no. Webtions are critical to the operation of the BJT. BJTs are also simply known as bipolar transistors. 8.1 INTRODUCTION TO THE BJT A BJT is made of a heavily doped emitter (see Fig. 8–1a), a P-type base, and an N-type collector.
