The solution and explanation is incorrect on so many levels Ninja. Verify your concepts and then upload videos. College students will learn and remember false basic concepts. Please Take care.

what would happen if Vin becomes 0 again? Will the Vx ramp down to 0 at exponential decay while the Vout ramps up to 0 at linear rate?

it wont saturate because of capacitor rating. It would saturate because of the limit of current source. If a capacitor has voltage rating, it might get fried.

A faster way is to assume input impedance is high (so an open circuit) and output impedance is low (so basically a short). In that case we are looking at the resistance of 3R in parallel with R + 2R which equals R/2.

You would use the buck converter as you won't have as much wasted power do to LDOs burning the current and kind of acting like a regulated voltage divider

My answer to produce the symmetric waveform: . . . . . . . . . I would use a transmission gate always fully on (pmos gate to gnd and nmos gate to vdd) so that its intrinsic R and C will delay the signal as the amount of delay we need. Then add on both sides a couple of inverter to regenerate the signals out of the TG. Otherwise we could use a CPL gate which can produce a differential signal starting from the single ended one without TG and the one inverted. What do you think about it?

How you arrive at your answer, the thought process, the assumptions and how you communicated those to your team mates are more important than being right. The best answer is arrived at when the team is in sync with each other. IC Design is a team play. I thought the circuit presented was a current modulator i.e. I2 modulates I1. Varying I2 varies VDS1 and I1 will change slightly due to channel length modulation by VDS1. But i enjoyed listening to your thought process.

For the Vout curve, shouldn't it decrease from 0 to -Vcc with an RC discharge profile rather than a linear downward slope (since this is an active LPF which would slow down any sharp edges such as a step at the input because they contain high frequencies). Please let me know if my understanding is wrong or if I missed something that makes the Vout drop linear instead of an exponential decay/RC discharge profile.

I'm about to have an exam in roughly a week that is exactly about this, so I'll either mess it up or get a good grade haha. But the thing is that this is an Integrator Amplifier, so the output is proportional to the integral of the input signal. As the input is a constant line, the output should be a linear function that over time saturates at -Vcc, as said in the video.

Another way to think about this is that as long as the Vx=0, the resistor current (=capacitor’s) is constant, so the capacitor is basically being charged with a constant current. Constant current means voltage ramp. Once the output rails out, this does not hold anymore

You’re being tricky so I’m going to be tricky with you back as an absolute strict hard definition without having given Measurement points or additional input output to the circuit outside of what has been drawn then strictly speaking without diagrammatic sample points it’s series/parallel until further notice, of course that has absolutely no meaning without local resistance measurement, therefor what you want to use it for becomes the relevant question.

Hi all, it never happens to me to see a sequence detector before, personally i would have suggest to embed some sort of "device id" approach, even if this implies having a dedicated id for each sub unit. Moreover, using a sequence detector could you possible have some strange situations in which the data stream you want to send to the subunit is seen by the sequence detector as a command regarding start and end stream, interrupting the process? Thanks for the video, could you suggest some book regarding basic "algorithms" and approaches in digital electronics, like the sequence detector you explained?

I would guess that the main reason is that it is safer / isolated from mains, low voltage. And that it was made possible bz the combination of advancements - LEDs and smaller cheaper SMPS instead of massive transformer that would have been required in the past.
