Analog Integrated Circuits Lab Added

Today on ClassNotes123.com, I just added the complete content for the Analog IC Lab, Phase Lock Loop design project which involved reverse engineering a National Semiconductor LM565 and reconstructing it with only discrete devices. The lab walks through the reverse engineering process, breaking down the circuit into each of its components such as the current sources and biasing, phase detector, amplifier stage, filters, Schmitt trigger, etc. This was followed by simulations, constructing the device and measurements. Granted, all the timing specifications were bound to be off given the discrete nature of the reverse engineered design, but a number of specifications were within a reasonable tolerance to the original spec. The lab pages are as follows:

Abstract & Project Overview
DC Current Bias
Phase Detector
Generation of Voltage Controlled Signal
Voltage Controlled Current Source
Schmitt Trigger
CA3046 & CA3096 Transistor Array Characterization
Experimental Verification & Conclusions

Added One More Electronics Lab Experiment This Evening...

I had some extra time to finish up one last lab for the evening on ClassNotes123. This lab is still part of the Linear Systems Analysis Lab course; dealing with a 2nd order voltage-controlled voltage-source Sallen Key filter in both a Butterworth’s and Chebyshev configuration.

Electrical Engineering Lab Experiments Added

This weekend I added the lab write ups for two different lab courses; Introduction to Electronics Lab and Linear Systems Analysis Lab. The intro labs focus on the basics, resistor measurements and tolerances, along with a lab on AC series circuits. The linear systems labs start out with an ideal op-amp experiment where a capacitance multiplier, virtual inductor, a power booster, and half-wave rectifier circuits are constructed and examined, along with Pspice simulations. The last lab in this weekends additions was a high-pass filter Chebyshev configuration with 2dB of ripple in the pass band. Links to each of the labs are listed below:

Resistance Measurements and Resistor Color Codes Lab
Series Circuits Lab
Ideal Operational Amplifier Lab
Sixth Order High Pass Chebyshev Filter Lab

Materials 1 - Course Updates

I’m working a bit backwards here on the Materials I course by getting up the last few chapter homework assignments posted first but it’s what I grabbed for this evenings work. I also made a few updates to the Materials I course page by adding a more detailed course topics list. Homework assignments I added include:

Assignment 6 - Carbon and Alloy Steels
Assignment 7 - Tool Steels
Assignment 8 - Stainless Steel

DC / AC Circuits Labs Now Online

Ok I just finished up the last of the three labs for the Circuits Analysis lab course, EE106. The first experiment, Circuit Response to Time Varying Signals was somewhat long that I split it over two pages; the lab objectives and procedure on one page followed by a second page of the actual Lab Write-Up and conclusions.

Over the next few weeks I will continue to get more of the electronic and electrical engineering lab courses uploaded. At this stage I’m more concerned about getting up as much useful content as possible for the readers; I’ll focus on page optimization and site rankings in the near future but I seem to be on a roll right now with the labs.
