This document contains an exam for a course on Analog VLSI Circuit Design. The exam contains 3 parts: Part A has 3 short answer questions worth 2 marks each about analog switches, current sources/sinks, and current mirror circuits. Part B has 1 question worth 8 marks about the characteristics of a controlled switch or distinction between DC and AC resistors. Part C has 1 question worth 16 marks about how bipolar and MOS transistors act as switches or the voltage-current characteristics of a BJT active resistor. The exam is for first year M.E students in the Electronics and Communication Engineering department and is out of a total of 30 marks to be completed within 60 minutes.
