This video talks about adding test points into the PCB.
frequency corners
มุมมอง 173หลายเดือนก่อน
This video describes the LTspice commands for calculating the corner frequencies. (3:15) It also describes how to sweep a capacitance to get a specific corner frequency.
Noisy Receiver
มุมมอง 180หลายเดือนก่อน
This video shows how to measure the quality of the receiver. This example has too much noise (noise is larger than the signal). It shows how to measure the performance.

This video describes what the noise signals look like and how to measure the signal to noise.
Non-ideal Op Amp
มุมมอง 3942 หลายเดือนก่อน
This video describes how to create a nonideal op amp. It also describes the nonideal parameters. (0:35) parameters from datasheet, (4:50) gain bandwidth, (6:40) slew rate, (8:50) current limit, (10:30) voltage limit, (11:50) offset voltage.

This video walks through how to layout the critical components of the laser tag receiver.
Fitting LED to model
มุมมอง 612ปีที่แล้ว
This video shows how to fit the data for an LED to an LTspice model. This video includes the following parts. (1:40) Extracting data from plot. (4:17) Fitting the data in excel. (5:45) Diode model. (11:20) Adding the LED model to LTspice. (12:50) Plotting the current versus voltage (IV) in LTspice.
ltspice copy

This videos describes how to copy a portion of an LTSPICE schematic from one file to another.
ltspice trig targ
มุมมอง 331ปีที่แล้ว
This video describes how to define the timing of a .meas spice directive. The trig is the starting time and the targ is the ending time.
Glad to see they moved on from Eagle. Altium is much more common in industry
Once again a banger from Ryan😤
I don't think this is up to date
thank you!!!
Thank you, needing to know tech to copy a schematic is crazy work though
Thank you! Thank you! Thank you! (why have I not found how to do this in the help file? I've been spending a lot more time in QSPICE these days; but, I could use it on the now rare occasions I use LTSPICE)
Whoever narrated this video has the voice of an angel ❤
Agreed, though he did forget to put those numbers in the description
@@samuelvandenberghe2173 we can only strive for perfection
Excellent! Thank you very much
Very helpful.
I hope you get everything you want in life
Real
This is great. Thank you very much!
Nice vid
Thank you very much
Thank you sir
What app are you? How can I get it at?
Dawg it’s literally on the tittle
The "Design Rules" tab is no longer the default option. They have replaced it with the "Constraints Manager"
I reckon you should have used a modulated sine wave so the FFT shows the carrier and its sidebands.
you are just perfect, thank you so much sir!
THOU SHALT NOT WIGGLE
New video posted let's goooooo
This video is from 2013
Ur all video awesome
Exactly what I was looking for. Thank you very much!
How can we find the FFT from the data coming from digital channels in an MSO
Do you mean from data saved from the oscilloscope?
@@stephenschultz6266 Yes sir.... For example, I have an IC of an 8-bit ADC and I am able to see the 8 digital bit lines on MSO. Now, I want to convert those back to analog form to obtain the FFT ? Is there any inbuilt function/DAC in MSO? How can I plot FFT from those 8 digital bits ?
The reason why you are getting what appears to be two stable phases when triggering is because the sine wave has a large amount of noise on it, so you are getting multiple rising trigger level crossings, including some on the falling edge of the overall waveform. To get rid of this, you can use holdoff as you show in this video, but an easier way that will usually work for cases like this is to enable "Noise Reject" which will add some additional hysteresis to the trigger, or to enable "HF Reject" which will add a low pass filter to the trigger path to clean up some of the high frequency noise components before triggering.
Great story
At 10:33, Isn't Vpi = Vin/(1+gmRE)?
Yes, you are correct. Sorry about the error.
@@ece3406 :) you are fine. I just wanted to make sure I am following it.
Thanks man
what is your simulation app name??
Absolute Legend. Thanks for the help. 10/10
Hi! how would you know the Dc beta, is Ic/Ib? thanks
The second method is not working for me, irrespective of how much I change BF my outputs do not change.
Is there a reason for not using a resistor on the source? I have seen solutions with both, a resistor on the source and without it.
A resistor on the source adds stability to variations in kp at the cost of decrease in the gain.
