How close are we to fabricating a germanium IC?
Silicon's advantage is not only its electrical performance, but also its chemical and mechanical properties which are also attributes required to make an IC in any practical sense.
As previously ...

How close are we to fabricating a germanium IC?
My personal opinion is that the substrate is likely to always be silicon because of cost.
(Talking CMOS now) as the technology has moved to FINFET and will move eventually to nanosheet or nanowire ...

How close are we to fabricating a germanium IC?
Primitive germanium integrated circuits have been in production in the USSR from the early 1960s all the way into early post-Soviet era of mid 1990s. They are used in the on-board computer "Gnom&...

Identify this 6 pin IC
It's very likely a PIC10(L)F320/322 MCU made by Microchip. I'm not sure what the second character of the marking is, but it looks like a C or G which would both be valid markings.
The part seems to be ...

7432 behaves like an AND gate & 7408 behaves like an OR gate
Just stumbled upon this and U had the same issue.
Try reducing the value of your pull down resistors. You may have a small voltage on your input pins 1 and 2.

I need help identifying a WL-CSP IC marked "14901 U25A" and "0120C U12A"
It's probably a Macronix flash memory chip.
Here are my clues:
This question about a chip with very similar markings which is likely made by Macronix (but not confirmed).
Both these websites (1 & ...

Help me to identify this IC marked '840M1D'
It's an On-Bright OB3840MP PWM controller.
I can't find a confirmed picture, but the marking style matches On-Bright and the pinout is plausible as well.

Identifying unmarked IC in CNC controller board
On my board the marking is not completely deleted. With some effort I read STC 15F104W, it appears to be a little microcontroller.
Here is a link to a datasheet for the STC15F101 serie which include ...

Why does current mirror need a diode connected configuration?
Short answer
Connecting a transistor's gate to its drain introduces negative feedback, reversing its operation. Instead of converting voltage to current, it now converts current to voltage. By ...

Current limiting in a ESC
Well, sometimes it isn't at all, not by electronic means I mean.
Strategies vary with scale and type, so this is a very open question.
When a very cheap/crude design is acceptable, or when the motor ...

What is this 5-pin SMD device marked "BAD"?
Pretty long shot, but it might be an Intersil (now Renesas) part with the marking code on the bottom.
I found this image of an Intersil ISL9003AIENZ-T using google reverse image search. The source is ...
