BJT Cutoff Frequency and Capacitance

BJT Cutoff Frequency and Capacitance: Device Cutoff Frequency – All transistors have junction capacitances. The junction capacitances and the transit time of charge carriers through the semiconductor material limit the high frequency performance of the device. This limitation is expressed as a cutoff frequency (fα), which is the frequency at which the transistor current gain …
