Early voltage in bjt

WebJul 13, 2024 · The voltage between the base and the emitter is apparently called "thermal voltage" and at room temperature it is approximately 26 m V. This voltage divided by the bias current gives the resistance r π. But normally in circuit analysis it is assumed that a transistors base-emitter junction has the voltage of a diode, approximately 0.7 V across it. WebVoltage Gain - (Measured in Decibel) - Voltage gain is defined as the ratio of the output voltage to the input voltage. Transconductance - (Measured in Siemens) - Transconductance is the ratio of the change in current at the output terminal to the change in the voltage at the input terminal of an active device. Collector Resistance - (Measured in …
