Which is the single resistor you wuld vary to set the gain?
How would you bias the amplifier?
Homework Answers
The given case is the case of intrumentation amplifier. The resistance R will decide the gain of the circuit. The output is given by:
The amplifier output follows the voltages present at the input at some amplification factor called gain. A bias voltage at the input allows the negative feedback of amplifier to bring the output at desired level. For this, replace the ground with bias voltage. There are three ways to bias an op-amp:
1. Voltage Divider Biasing:
2. Voltage Follower Biasing
3. Split Resistor Biasing
