*Questions attached

1. a) Determine the voltage gain (AV = VOUT/VIN) of the amplifier circuit, and the value of VO.

b. Assume that the 2V source is replaced by a variable voltage source, VS. Find the allowable range of VS that will keep the op-amp operating in the linear region: (-VCC ≤ AVS ≤ +VCC)

2. Determine the value of iL

3. a. Determine an expression for Vo in terms of VS.

b. Find the allowable range of values for VS that will keep the op-amp operating in the linear region (-VCC ≤ AVS ≤ +VCC).
