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 …
WebJan 20, 2024 · Voltage gain for a common emitter amplifier (for instance) is determined in part by the collector resistor. Put simply, the higher the value of collector resistor the more output voltage signal for a given input signal. WebIn this video, we will discuss non-ideal behavior of bipolar junction transistor. So, the first non-ideal behavior that we want to discuss is the Early effect. In the previous discussions on active bias, the current is entirely determined by the base emitter voltage.
