I thought the same thing, but if you’re tinkering with these circuits you likely have an op amp chip with some unused channels since there are four per chip.
hmmm could you make this Stereo ( dual mono) by making 2 configs( left and right)- 8 mono for left going to 1 left and then 8 mono right going to 1 right? or is it not that simple lol
So… you literally made a “Transistor VCA video” With NO FUCKING TRANSISTORS…. Bro I hate the internet I hate ChatGPT Fucking impossible to ever get clear directions to do anything
Tyabk you for the amazing explanation. If i understand correctly, then, the reason why we often use a current mirror as a tail current generator, instead of a resistor with fixed potentials, is that the current mirror will *ideally* feature a very high output impedance, thus since this is featured at the denominator of the common mode gain, this means that the common mode gain will be hugely reduced?
I've got two questions. 1. Can I use this differential amplifier in parallel with a load. 2. Do I need to impedance match the differential amplifier to the load impedance
I dont undertand how this will be very stable power supply. Zener drop voltage depends on current and current will not be stable here, because Vin in not constant.
It's worth noting that it is _disadvantageous_ to use larger filter capacitors than is necessary. This is because the power dissipated in the linear regulators is the product of the average voltage across the regulator and the current drawn. By using capacitors that are only a little larger than the minimum needed (allowing for tolerances, of course), you maximise the ripple voltage, which consequently minimises the average voltage across the regulator and hence minimises the power dissipated in it. It also minimises the inrush current on startup and maximises the conduction angle, so this is a good example of not over-engineering a design.
The Paia VCF design is very interesting. As to minimize the load of the following simple transistor amplifier, you changed it into a more complex bootstrapping-stage ... but would it not be simpler to add an emitter follower between the filter part and the amplifier part?
You deserve millions of subs, for such good beginner videos! :) I am a retired electronics engineer and I always struggled to explain in simple terms to juniors, and you do it GREAT!!!!!!!!!!!!!!!!! :)
Good video. Here is a Wien oscillator using a light bulb instead of a fet. It's based on an HP signal generator. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RoAXHHhjECM.html I have 2 other examples on my channel.
I know this is an older video but i just want to say thank you so much for your in depth explanation and example schematics. This video was the inspiration for my senior design project where me and a partner built a really cool modular synth style guitar pedal with a 3-notch phaser and all of the notches broken out with 3.5mm jacks. We also made a whole stage of digital effects using a Daisy Seed and because of your channel, my partner and I graduated last weekend with BS's in electrical engineering at the university of florida. Much love!!!
Actually, no electronic device is 100% perfect, it is currently not humanly possible to make electronic components that are 100% perfect, even a simple copper wire isn't 100% perfect.
