WebMay 22, 2024 · If this amplifier is used for ultrasonic signals, the capacitive reactance, X C, would be as low as 160 k Ω at 100 kHz. Although this is high compared to typical BJT circuits, it's less than the R G values commonly used for biasing. At higher frequencies, the situation is even worse as X C decreases with frequency. http://www.ittc.ku.edu/~jstiles/412/handouts/5.6%20Small%20Signal%20Operation%20and%20Models/Example%20A%20Small%20Signal%20Analysis%20of%20a%20BJT%20Amp.pdf
