D. 6.65v
Answer:A
= gm×( Vin1 – Vin2) = 0.065 Ω-1×(4.9v-2.5v) = 0.156A. 9. Calculate the VI – VO for the level shifter shown in the figure (Assume identical silicon transistor and very large value of β). Transistor QA and QB form current mirror.
A. 5.56V B. 6.00v C. 7.98v D. 6.65v
Explanation: Since the transistor QA and QB form current mirror, ICA= ICB = I.
