This video contains Differential Pair Layout in English, for basic Electronics & VLSI engineers, as per my knowledge shared the details in English. I used CADENCE VIRTUOSO 45nm BULK CMOS process,
matching is very important for any analog circuit such as a differential pair, Current mirror.

What is a Differential Amplifier:
A differential amplifier amplifies the difference between the two input signals. It is widely used in integrated circuits as an amplifier.
The first stage of the op-amp is also a differential amplifier.
Two perfectly matched MOSFETs with identical characteristics are used in a MOS differential pair.
In the integrated circuits, it is possible to match the characteristics of the two MOSFETs to some extent.
Advantages of Differential Amplifier:
1) The ideal differential amplifier eliminates the common-mode signal at the output and only amplifies the differential input. Using the differential amplifier it is possible to eliminate or reduce any noise or interference which is common to both input terminals.
2) When multiple differential amplifier stages are cascaded together, then it also eliminates the use of coupling capacitors between each stage.
This video will be helpful to all the students of science and engineering in understanding the basics of the MOS Differential Pair.

I apologize, I shared the wrong window while doing the layout. I am adding some pictures in the comments section that will help you. I also added a short video and here is the link:

Great work❤ and do a video on current mirror matching and resistor matching
Will try,
