Paper format. National Exams, May 2015 — 07-Elec-B5 Advanced Electronics. Three hours, CLOSED BOOK, any non-communicating calculator permitted. Five questions, 20 marks each; all five must be answered. The paper directs candidates to state any assumptions made, to treat ground and chassis as common, and to assume ideal op-amps on ±15 V rails unless a question says otherwise.
Reference texts. B. Razavi, Fundamentals of Microelectronics, 2nd ed. (Ch. 9, Cascode Stages and Current Mirrors — Question 1 cites Example 9.9 by name); A. S. Sedra & K. C. Smith, Microelectronic Circuits, 8th ed. (Ch. 8 Building Blocks of IC Amplifiers, Ch. 9 Differential and Multistage Amplifiers, Ch. 10 Frequency Response, Ch. 12 Output Stages and Power Amplifiers); P. R. Gray, P. J. Hurst, S. H. Lewis & R. G. Meyer, Analysis and Design of Analog Integrated Circuits, 5th ed. (Ch. 3–4 for the current-source-loaded pair).
How the figures were recovered. component placement, which terminal the input drives, and whether a load pair is a mirror or two independent sources. Where the printed data and the drawn topology cannot both be satisfied, the reading adopted is stated in a check note rather than silently chosen.
