hello,
I tried to calculate the voltage gain of an NPN transistor diode, but when I do I find my calculates a function of a low pass filter of the 2nd order or is asked to find a function of the first order form F = K / (1 + p * w0)
help me please.
thank you

You will find attached the circuit diagram.
they say in the exercise that the transfer voltage is provided
by bipolar transistors Q1 and Q2. and at least a first approximation, we will consider that the voltage transfer β (s) will be limited in frequency by the transistor Q1 connected in diode.Show that β (p) = K / (1 + p * w0)

azerty1, two questions:
* Are both collectors really open circuits?
* If wo should be a frequency and p the complex laplace variable, you will have a problem with units. Check this formula!
not both collectors are not in the air, but they just interest to emettors so they did not put the full scheme.
for the 2nd question, the formula is correct it resemble to the transfer function of a low pass filter of the first order and wo be a pole of the equation.

OK - in this case I cannot help you.
You should at least be able to use any textbook or internet search to find the correct formula.
Do you know the meaning of the symbol "p"?
