By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the value of R2 as this resistor sets up a voltage divider with the very small input ...

If the input voltage has an offset or bias that must be removed, then we need to modify the circuit. A positive offset can be accounted for by adding a corresponding reference voltage in series with ...

Jenny, I love this series, but paragraph 4 of the common emitter biasing discussion should say, “In an NPN transistor, the connection between base and emitter is a PN junction, so as you might ...
