Problem
1. Design a circuit that can shift and scale the voltage from the range of 2 V - 2.5 V to the range of 0 V - 5 V.
2. Suppose that there is a 10-bit AID converter with VREF = 2 V and VREF+ = 4 V. Find the corresponding voltage values for the AID conversion results of 40, 100, 240, 500, 720, 800, and 1000.
