Pre-lab Tasks:

1. Design a non-inverting op-amp circuit that has a gain of two. Show all of your analysis work, draw a schematic diagram of the circuit and explain how the circuit works.
2. Design a comparator circuit that compares a reference voltage generated by a 10 kilo-ohm potentiometer against the input voltage generated by your buffer circuit. Your circuit should generate a voltage that is either 0 or 9 volts. Draw a schematic diagram of your circuit and explain how it works.
3. Design a clamp circuit that clamps the comparator's voltage to either zero or five volts. Choose the resistors so that the maximum current drawn from the source is around 1 mA. Show all analysis work and draw a schematic diagram of your circuit.
4. Draw a picture showing how you plan to breadboard the three circuits and connect them to the DAC circuit.
