I am trying to calculate and simulate the output resistance of a stacked NMOS transistor used as current mirror load and I have a few doubts about hand calculation and simulation setup. The circuit ...

I have the D1 MINI ESP32 board which shall be battery powered in my project. For this I am experimenting with deep sleep to conserve power as much as possible. While the ESP should only take microamps ...

I have been told that the circuit, attached in the image, has the same current flowing into it as out of it, in regards to the two terminals with the voltage \$u_z\$ across them. It is stated that the ...

First part of the research here. Some news about the progress of my research: the fan is running! Well, almost. This fan operates on DC-LIN or LIN over Powerline Communication. So I built an ...

My design is found in the link below. I've breadboarded it and it functions. I was wondering if there are any flaws in it. on falstad.com

I'm fixing an old headset (Left and Right speakers + Mic) that had a cut cable. I bought a TRRS female socket, and an auxiliary "TRRS-male to TRRS-male" cable. With a couple of tests I'm ...

I am designing an LED matrix for an LED lamp. I need to calculate the heat dissipation from all LEDs which is the dissipation of one LED times their number to choose an appropriate heat sink. The ...

This paragraph is from The Art of Electronics third edition: Some more home-grown philosophy: there is a tendency among beginners to want to compute resistor values and other circuit component values ...

I need to detect when a 24V pump turns on. I've decided to do this using an optocoupler. Could you please tell me if my circuit is correct?

How to access the AFE4960 Two-channel ECG analog front end with integrated respiration and pace detection register map? Why doesn't TI company provide that directly?

Quad Flat Package is a rectangular component package with "gull wing" leads on all 4 sides. The smallest common package is QFP-32 (8 leads on each side). The question is specifically about ...

My fellow electrical and Electronics Engineers, I know there are a lot of young engineers or starters here, who I need a guidance on electronics circuits design. So, what's the way for one to learn ...

I need to implement an analog circuit based neural network. I haven't found a proper reference to implement it from scratch. Any leads would be appreciated

I am struggling to remap a backspace key which undo last segment during routing. I do not like this key being backspace and I would like to have it on a different key. The problem is it does not have ...

I'm using buffer SN74AVCA164245 and I feed one of the I/O with 20V and using voltage divider, I expected to see 2.34V on the input of the Buffer and to see 'High(1.8V)' on the output of the buffer, ...
