Miller Effect (16-Transistors)

- Parasitic capacitances are worse when you have inverting amplifiers. For example, the common emitter configuration will have reduced performance at high frequencies than other transistor configurations. Why is that? That's what this video is about.
Aaron Danner is a professor in the Department of Electrical and Computer Engineering at the National University of Singapore.

I really like how the professor gradually deepens the study of this topic. Hopefully, in the end, we will have to design a real amplifier.
Excellent
Great lectures!
Hi Prof! Same effect coming from the Avramenko plug with square wave, or the ZVS circuit... or ChatGPT .. my circuit the ZP1 circuit. Actually quantum plasmoid energy information transfer happening. Nikola Tesla radiant energy, or cold electricity.. Parasitic... c'moon Prof.! 2 zener diode, anode + chatode solder it, and in one pole, square wave, because of harmonics. Solder on 2 legs the LED, and you can hold in in one hand, just one leg of the diode. This is the avramenko circuit. Able to get the radiant energy... this is not Earth ground or normal capactive circuit. Because this has different properties! If you take just a little small wire on the LED and you not holding it... it will work as well! Please chech the ZVS circuit... easy to increase with a MOS fet, plus transformer coil.
i have found in practice and documentation that Cbc X Beta is quite close in approximating Miller capacitance. it's not exact, but close enough for most design work.
Thevenin is actually pronounced Thay-vuh-nin. I pronounced it wrong all the way through college and for another 10 or 15 years, so... That was a great short lecture on the Miller Effect and all my professors also mispronounced Thevenin too. Al-you-min-ee-um is also technically, by some antiquated rules of the periodic table and the elements, a perfectly correct pronunciation of "aluminum". Brits and old American men used that pronunciation for aluminum. Archibald was one of those old men. He was one of those freaks who could darn near do fast Fourier calcs in his head, but in the lab he started more fires and blew up more stuff than everyone else combined. RIP Archie!
Awesome video. Thank you very much!
The best video out there of theoretically explaining what the Miller Capacitance is at the example of an amplifier.
Most of them go directly and speak of Miller capacitance on transistors, but that is just a specific case.
Thank you professor for your channel ❤
Classic , exemplifying and thought provoking
Great Sir
Thanks, Tamil, Sivaganga Dt
Lovely stuff!
Thanks!!!
Battlefield 3. It’s so funny.
thank you very much Sir
The 8pf (Miller) capacitor is charging and discharging as the collector voltage rises and falls with the driving signal changes and the gain of the amplifier will determin the range of voltages that the 8pf sees. More gain will produce larger and more speedy voltage changes. Therefor the Miller capacitors effect will vary with frequency. Am I correct?
Hi there, the charging and discharging of a capacitor depends upon the the frequency and the source voltage magnitude as well as the capacitance itself, now lets say the frequency of the input signal and the output signal is same, no wonder that the 8pF capacitor have less capacitance than base to emitter junction which is 22pF , but since the input and the output voltages are 180 degree out of phase with each other, there will be a more potential difference, not to mention that the output voltage is also getting amplified, therefore the difference will be more and hence the charging and discharging of a current at collector to base junction will be more than base to emitter junction.
At 9:26 in this video: When calculating Re (emitter resistance), where does the value 26 come from? Is that a static constant? I can't place it. Thanks!
It's k*T/q at room temperature, so it's almost a constant.
This is such an important topic, great vid
Can we have cascode?
So hard 🫣
