Apologize for our non-technical audience since this quiz is more for our FAEs...
A kind proposal from our colleague Martin Walker, ADI Product Marketing Engineer, UK:
Most of our electronic engineers have seen this sort of circuit in their first year study time using a bipolar transistor in its 3 famous basic configurations: common emitter, common collector and common base.
Here above is a common emitter configuration.
- Vcc = 6V
- Vout = 3V
- Tc = 25°C
Q1 is a BJT NPN with current gain β of several hundreds.
RB1 and RB2 are large compared to RC and RS
- Is there enough information to work out the gain of this circuit?
- If so, what is the voltage gain of the circuit?
- Is it a good amplifier?
- If not, what would you do to mitigate for its limitations?
Again, many thanks Martin!
