I get a phase shift of 90 degrees between voltage of the capacitor and current through the capacitor which doesn't make sense it should be 45 degrees You don't need a whole circuit to see that the...
I have a battery pack that consists of 18650 battery cells(14 cells in series max.). Hence, the voltage of the battery pack will be between 35V and 60V(to be on the safe side) I am designing a BMS...
To summarize the problem, you have 12 V battery packs that you don't want to change due to certifications, but you need to power a 48 V 4 A load. The battery system also needs to be compatible wit...
R22, C22, C23, together with Rfbt (feedback top) and Rfbb (feedback bottom) form what is called a type II compensator, using TL431 as an opamp with built-in reference. The feedback network is a bit...
Since this is homework, I'm not just going to give you the answer. When all else fails, go back to first principles. That's what handy shortcuts, like using impedance, were derived from. In this...
Your question is quite long, so it's not clear what exactly you are asking. It seems the main point is what Microchip means by Note 5 on page 7 of the datasheet: You are right, that makes no se...
Question: What is the purpose of the current mirror? Answer: It allows to combine the current changes in BOTH transistors (T1, T2). Explanation In a classical differential amplifier (with separat...
I'm not going to get into how to model the PHY interface, but will try to explain why there are differences. The type of Ethernet you are talking about is transformer-coupled. The line itself is ...
Your basic idea is fine, but your implementation is not. C1 makes the whole thing not work, as it will block DC. C2 puts a burden on the switch. D1 would preferably be Schottky. I'll write a mo...
What is seems you really want to know is how to size a power supply filter capacitor, not what the input capacitance of something is. The objective is to keep the ripple voltage below some value. ...
Your derivation is correct, you just missed the sign: $V_L=-V_C=2;\mathrm{V}$, because the capacitor charges with +2 V, and the discharge accounts for the negative sign on the inductor. The notatio...
How does the differential to single ended converter work? In order for the circuit to work, Q1 and Q3 must be in the saturation region and depending on the voltage inputs, one of Q2 and Q4 will be...
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...
To be clear and protect against possible future edits, here is the circuit being discussed: As you say, this is a differential to single ended converter. In this case, the MOSFETs have likely b...
Suppose we have this circuit which is supposed to be an unbalanced frequency mixer. But how does the diode generate a signal with new frequencies at the output?
Which important system design parameters need to be locked in order to estimate the maximum allowable level of the input voltage ripple of an SMPS? I have encountered ballpark figures of <1%, &...
I have designed a PCB that I need to work in which a microcontroller drives a 24 V brushed motor. The input power to the board is 24 V, this is then lowered to 5 V by a step down converter, and thi...
If your question is theoretical (you are dealing with ideal components), then the answer of Olin is just fine. If it is concrete, that's the answer of Andy. In the concrete case furthermore, I wou...
I think this is partly semantics. For example, consider designing a compensator for a power supply. The transfer function under consideration is essentially the open loop impulse response of the ...
I think this would make a good Paper. I know you want others to collaborate, but that's something that doesn't really work. "Community Wiki" certainly never worked right on SE. Too many cooks ma...
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'd rather use the AD4111 as a high-side current sensor, instead of creating an "inverter" which would generate an equal and opposite current. Each current input of the AD4111 (IINx+ and IINx-) is...
The 45° routing makes it easier to route multiple parallel traces across the PCB - I would say that's the main reason why they are so popular. Whereas 90° turns of multiple parallel traces next to ...
If you put the Fat load-dump TVS downstream of the reverse-polarity protection MOSFET [1], then the load dump current would have to flow through the MOSFET. The MOSFET would have to be rated for t...
Using a P FET for polarity protection like this means that in case you flip + and -, the gate will be inactive, meaning that GND which is now connected to drain will get disconnected - no current w...
