5. A ferromagnetic core with a constant relative permeability of 1500 is shown in the following figure. The core depth is 9 cm, and all dimensions are as shown in the figure.The air gap length on the leftmost column of the core is 0.5 cm. Because of the fringing effect, the effective area of the air gaps is 4 percent larger than its physical size. If there are400 turns in the coil wrapped around the center leg of the core, - Draw the magnetic equivalent circuit of the system. ) Find 4, l2, l3, l4, l5, l6, and l7 in meters. ) Find cross-sectional areas in each section of the core in m² and name them as A1, A2,A3, A4, A5, As, A, , as well as Aag for the air gap considering the fringing effects. d) Find all reluctances in the equivalent circuit. Calculate equivalent reluctance seen from the coil. Calculate the inductance of the coil. (

3. Using PSPICE (or alternate) Build a CMOS inverter as in the figure. Set up a DC sweep simulation that sweeps Vin from 0 to 5 V in 0.05 V increments. Run the simulation. If everything was set up correctly,the voltage transfer characteristic (VTC) should be plotted.

On Figure P4a, you have a Common Emitter (CE) NPN BJT amplifier. Notice (unlike the circuits that we have studied in class) the absence of a source resistor R sig and load resistor R,. If we know how this L·amplifier behaves without Rsig and R, we can infer its behaviors if Rsig and R, were to be added.
