I want to create a schematic symbol and reuse it for multiple ICs which have identical pinouts. For example, OpaMPS, or the venerable SN74LS00, SN74HC00, SN74HCT00. How can I do this in an Altium...
This is about as simple an analog inverter that I can simulate, but warning, not for the beginner with resonance issues. The bridge diodes are 2f multipliers reduced to logic level with divide by ...
There is no "simple" circuit that does the reverse conversion of what a full wave bridge does on a sine wave. However, it is possible to get there from here. Most of what you are asking about is ...
I am generating files for manufacturing my design in Altium 22 and ordering through Eurocircuits. What I noticed during the ordering process is that the rotation of many components (and sometimes ...
Summary "Outdated" should be used for "this won't work anymore today", not "we would do this differently today". Detail "Outdated" should be reserved for when an answer is wrong or misleading be...
Hi guys,I'm designing a multiple output flyback converter with 2 outputs at 10v@1 Amp and 5v @ 2 Amps .Input is 20 V dc Im having some problem with the implementation of closed loop. Open loop res...
Someone just created the tags 208VAC and 230VAC. If think we need to create a policy about tag usage related to supply voltages. Clearly, stating the supply voltage is highly relevant information ...
On page 26 and 27 of that manual, it lists accuracy and resolution separately. The accuracy is how far away you should expect the measured value to be from the actual value. The resolution is the...
Assuming you speak of UART, then the receiver must be told in advance the number of data bits, the number of parity bits and the number of stop bits. The start bit is a logic zero (low) and the sto...
You might get lucky and be able to measure the input resistance using this method. It should work because the black socket (common) is shared by all measurements.
This answer is regarding the resonance issue that C2 is fixing, and how it could be done with a smaller cap. There are two aspects of it. To start, consider the 5.6uH vs the 10uF capacitors. It ca...
Example of answers that should be classified as Dangerous: "Do it yourself" Q&A where someone is fiddling around with 230VAC electronics or other such potentially lethal power sources withou...
From the point of view of the SPI peripheral (and any debugging tools you have directly connected to the SPI bus), there is no difference between SPI stream and memory-mapped SPI. The difference i...
That's a rather strange thermal relief pattern. It's also not clear where the hole is supposed to be. A proper thermal pattern has a plated hole and annular ring around the hole as usual. Then t...
You start by checking the forward voltage and rated current for the LED. 20mA is the usual industry standard for regular LEDs and the forward voltage will be specified for that rated current. In t...
What the "appropriate" value of R1 is depends on what you are trying to achieve, which you haven't told us. Will this device be used in bright light, like outdoors, and the LED therefore needs to ...
I have a problem which I don’t understand how to solve. I have this 2-bit adder, but when I select A1AO to be (11)2 3 and B1BO to be (11)2 3 and run it on Logisim it doesn’t show me 6. Instead it s...
Reasons this is sometimes done: To get higher power dissipation. To get higher voltage capability. To get lower parasitic capacitance. For 1 and 2 the "normal" answer is to use a resistor rat...
Whichever you choose. I notice that you deliberately made the gain of one transistor a little higher than the other. That is irrelevant. The positive and negative outputs don't depend on the pow...
I see you already have an answer based on the device physics. I'll answer that this means in a circuit. BJT (bipolar junction transistors) do work in reverse, at least somewhat. Generally, the c...
"Stream" and "memory mapped" should be defined in the documentation for whatever microcontroller you are using. "Memory mapped" can mean different things. It might be just a different way of sayi...
You can use various methods for it, one way would be to simply use the ideal transfer function and make it in parallel with $R_o$: $$\begin{align} A(s)&=R_{th}+\dfrac{1}{sC_{th}} \tag{1} \\ ...
I am designing a DC/DC converter in the control loop of which a transconductance amplifier (OTA) is used. This part of circuit looks like this: To determine the needed characteristics, I am usin...
I think such questions are OK as long as they are EE-specific. General purpose dictionaries often do a poor job with specialized technical terms, especially when they are the same or similar as re...
What is a typical value for capacitance of a real inductor? "Typical" capacitance is a useless to design circuits with. It will also vary considerably by inductor size, geometry, and materials us...
