1. Toughest question asked (in my opinion, as it required creativity and knowledge to answer) was on writing the following function in Verilog: W = .5X + .25Y Where W was an output, and X/Y are inputs. 2. If X/Y where 4 bits each, what is maximum output number possible?

Two questions regarding MOSFETs, 1. The first question was to identify a MOSFET circuit, 2. The Second was to explain the difference between the parameters of two of the MOSFET devices in the circuit. 3. The third question was to write down sample code for a scenario.
