Thank you much. I was stuck at the voltage headroom for the cascode current mirror for so long. The book made no sense, and following your analysis took me no time in understanding. Great video!
Excellent video and tutorial. Thank you for your efforts to teach the world. You might like to know that you are reaching not only electrical engineering students, but retired hobbyist, such as me. As hobbyist are not used to working with the short-hand language of the electrical engineering world, may I request that you speak the entire name of the variables that you write in short-hand... Such as when you have written "Vgs," every time you speak that reference, please say the complete term "Voltage (from) gate (to) source. This will help those less acute to the language to hold together their(my) understanding through each step of the circuit, to its conclusion. I intend this as no criticism, but offer the suggestion in appreciation of you sharing your expertise. I do have questions... Is the Wide Swing Cascode Current Mirror the best precision current source circuit that you know of? If not, then what circuit would you prefer, given no constraints of costs, etc? Each subsequent "improvement" to the basic Wilson Current Mirror adds components, and, therefore, the addition of more elements that are subject to thermal drift. Adding MOSFETs also increases the time required for the circuit to react to changes in voltage. Might an earlier variation of the circuit provide similar accuracy, with fewer components and their associated cost? What variation of the circuit proves to be the best compromise? I became slightly lost with the idea of a smaller MOSFET, i.e. "1/4(W/L)." Please explain not only the words of the term, but the implications for selecting the particular MOSFET for this component. I look forward to your reply. Now, I am off to see if I have five NPN MOSFETs, with which to build the circuit on a breadboard. I will add a potentiometer, in the place of the current reference (Iref,) vary the current and fascinate myself, by watching the current remain constant.

this is perfect..thanks..this same question came as a quiz,,,was so happy !!!!!!......
I am glad you found the video useful. You can see the all the playlists at ruclips.net/user/mateoaboytube

Thank You
The format could be better but the explanation is perfect. ty
Thank you! Helped a lot
great teacher
hi mam , could you please tell to write digitally what you use ,,, i need to buy
MSPaint
Done
Your handwriting are too small. Thanks for explaining though
Thanks
