I am looking at various DC/DC converter topologies for a power system I am designing. The most suitable topology for me is one that can perform both step-up and step-down functions, so I am looking...
The premise In a recent video by the pop-sci channel Veritasium, the concept of the flow of electricity and energy transmission in a circuit was discussed. In that video a thought experiment is pr...
This question popped up in the feed and I got curious. Here is what I could find. Note that I am not an IC engineer so my interpretation of some facts may be off. The 3.3V level is defined in the ...
New versions of Altium (22.x) changed their approach to component libraries. You now create components, to which a symbol and several footprints can be tied. This allows you to reuse symbols acros...
Let's take a soft-start circuit that looks like this: To my understanding, the function can be described as follows: C1 charges to open the gate. Value of C1 will dictate the soft-start delay...
In the field of DC/DC conversion, one can build a synchronous DC/DC converter (also referred to as synchronous rectification). This practice involves replacing a diode with a MOSFET switch. As far...
Most CAD packages use a "symbol" and "footprint" library approach when it comes to designing schematics and PCBs. Some (like recent versions of Altium) have "component" libraries where symbols and ...
I am designing a PCB with somewhat limited space. To save space, I am placing some vias on component pads. However, I am not sure if this is a good practice in PCB design. As far as I understand, t...
I am looking to improve my knowledge of embedded systems programming, specifically regarding microcontrollers and embedded Linux systems. A lot of the information that can be found regarding C/C++...
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 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 ...
I think the Papers section can be suitable. In the category description post it says: Example of paper topics: [...] A survey of scattered information, with the paper putting it all in one place...
I am working with an IC that uses a partially intergrated regulated charge pump. The circuit looks like this: It behaves like a voltage doubler. However, when looking at other regulated charge p...
Most modern CAD software for PCB design offers arc trace routing or a form of conversion between 45/90 degree angel trace routing and arc trace routing. Despite this, the overwhelming majority of c...
In noise analysis of operational amplifiers, the following is considered: Noise generated by the external components (resistors in feedback network etc.) Noise generated by the operational ampl...
In the design of a power converter, picking the appropriate capacitors for the input and output of the converter is quite important. It is relatively easy to calculate the necessary values for a gi...
I was reading through the datasheet of a boost converter, TPS61023 from TI. In the "Input Capacitor Selection section", they give the following advice: 8.2.2.5 Input Capacitor Selection Multil...
Let's take a look at the state of affairs for the past few weeks on this forum. For the past two weeks, some users has been posting a lot of questions, a lot of them self-answered. This is not a p...
It seems to me like the goal of the proposed change is to fight vandalism. I am pretty certain that no online forum has found a way to stop trolls, simply because trolling is one of the ways people...
