Microelectronics Assignment 7

Document your work in a Microsoft Word document or PDF. Show netlists for all Spice calculations. You must submit your JELIB files and SPICE schematics and other associated files.

1. The circuit below is a TG-based OR gate (See Baker figure 13.11). Generate a symbol and circuit in LTSpice for a transmission gate, and a test circuit to verify the operation of the OR gate. You should create an OR symbol and circuit and a separate test circuit that instantiates and tests the OR gate.

   

2. Use MODSIM to verify the behavior of a NOR gate (built from transistor PMOS/NMOS objects). Follow the example of the NAND gate shown in class.

3. Layout and test a multiplexer in Electric. Your layout should include the inverter needed for the complementary control signal. You will need both schematic and layout versions of the multiplexer and a test circuit in Spice.

   

4. Layout and test the latch shown below (see Baker figure 13.20). Use Electric for the layout and LTSpice for the simulation. Include the layout needed for the complementary control circuit.
