Absolutely brilliant lecture. I love op-amps and have always wanted to be able to think more deeply on how to design with them than "here's this configuration. just change the component values until it works". Your idea of "Think of it like a voltage teleporter" makes it so much more intuitive! Thank you for that! Side Note: hearing an accomplished professor say "My Headcanon for how this circuit was designed" is hilarious and absolutely made my day. I truly love how you present things lol.
Thank you for this. This video-lecture series is really underrated! You're so much more precise with your language and call-outs of your assumptions than most other people on the internet (not just TH-cam) covering similar topics. As an amateur who wants to learn more about analog electronics after my day-job, I really appreciate the work you've done to organize, curate, and publish this series.
I wish my university lectures were like these. I would have loved electronics, instead of hating it. Well I'm now 52 and enjoying it, better late than never!
Brilliant series on opams, thank you! I wish there was something like that, an intuitive explanation of how things work, but for transistors. It is strange, but I feel more comfortable with opamps than transistors (shrug)
It helps me to try to put the "semiconductor quantum physics" shenanigans aside, (except for keeping in mind that the diode junctions involved will have a small voltage drop I can't ignore), and thinking of a transistor like an electrically controlled water valve. a small signal on the base (or gate for fets) controls the current flow between the emitter and collector (or source and drain for fets). My main issue with transistors is trying to keep track of all the different types, especially for MOSFETS. But I suppose if you do what this video suggests, and think of what task your circuit needs to accomplish first, and the environment it will be operating in, that should narrow down your component choices. (i.e. he chooses to use capacitors because they are more practical for audio circuits in terms of price and stability than inductors. Similar lines of thinking can make the choice between the various types of transistors easier to make as well).
Even a modern ingnition is based on an inductor/coil there no mechanichal distributor and contact breaker, which are replaced by tranistorsn or ic-dricers but you still need the coil to get high voltage/spark
my design of the Buchla VCO shows >1mA / 950 micro amp at 8kHz, discounting the consume of the opamp and LM311. It doesn't need the "symmetry" potentiometer + the 10M resistor, on top of the long tail, need a trimmer elsewhere. but is required to use a alternative overall power supply. 1.6 mA @ 15kHz. 400 micro Amp @ 1kHz. But seams to be very picky around the npn trannie to sink the current. You would probably like it, without a formal degree.
@@CarlosValeraLeon Oh! yeah, if that's what @oneRella is referring to, that's just a scripty way of writing v. So v_c is the voltage across the capacitor.

Excellent explanation of the integrator/differentiator circuit. I finally understand this.

Much needed tutorials, Thanks professor.

Unconventional explanation but it helps to refresh my brain cells :) thx 🙏
Super cool and insightful!
Does the video end at 21:12 on purpose?
2112?

I can't believe I am watching these lectures to entertain myself

What is “C” and n this math?
C is the capacitance of the capacitor. Not sure which "n" you are referring to?
@@Lantertronics Maybe "n" refers to the way you write "V" for voltage?
