1. Two non-OP AMP circuits need to be connected in cascade. Explain why using a follower is more useful than simply connecting the two circuits using wires. Are there any downsides to using a follower?
2. For the circuit in given Figure:
(a) Find vO in terms of vS.
(b) Find iO for vS = 1 V. Repeat for vS = 3 V.
