Complete the following circuit so that it becomes a bistable circuit with two stable states (and one metastable state). b. (12pt) Modify the circuit by adding two transistors such that the state can be changed by applying proper inputs. (Label the inputs as Set and Reset on your circuit) c. (12pt) Is the size of the transistor (that you added in part-b) important for proper the operation of the circuit? How should you size it? Why? Explain in detail.
