CMOS 4-to-1 Multiplexer (MUX) Digital IC Design Project Report
Budget: $30 – $250 USD
Perform the following:
Design of 4-to-1 Multiplexer (MUX) using both cases of (1) only transmission gates (TG) and (2) conventional CMOS gates. Compare the TG design with conventional CMOS gate designs by performance, power, chip size, number of transistors, etc.
For a report, put the following as a guide for your own design:
1) Draw logic symbol, schematic for simulation.
2) Draw stick diagram and Euler’s paths
3) Electric Schematic & Layout
4) LT SPICE and IRSIM where needed to show performance
5) Verify your design by putting pulses to see the outputs.
6) Complete a Truth table for the MUX.
7) Find a Boolean expression for the MUX.
8) Run LTSPICE in Electric to "plot" waveforms of Vinputs and Vout. Use 100ns
period, 5ns rise time (tr) and 5ns fall time (tf) for Vin. Use 50% duty cycle which means 50% logic high and 50% logic low levels.
1) Measure the output waveform by taking measurements for tr, tf, TLH and THL for the first input, D0. You should name the other inputs D1, D2, and D3.
2) Write some paragraphs for design and measurements and make a project report. Write Figure numbers and captions. Attach the cover page. Follow the IEEE formats.
