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?
Miss Mulan - I am a bit late with my answer. Nevertheless - there is formula which gives you the necessary filter order "n" - as a function of two frequencies and both associated damping figures. ...
Unless you know the exact formula for the I-V curve, you will never find out anything analytically. Fair warning: very unlikely you will get such formula, since they are strongly non-linear in natu...
[In addition to what Olin wrote earlier.] I looked-up one of the references from the textbook, and I may have found the answer which the author had in mind. This entire spectrum must not be pas...
If you are pursuing engineering then you can't use doodles instead of schematics generated by dedicated (or not) programs. It will take you just the same amount of time, if not less, and the result...
A resonator cannot replace a filter because the filter has multiple resonances to extend the bandwidth. For AM carrier modulation using a narrow band resonator with 0.5% tolerance of 6MHz or +/-30...
I have a design of a power line communication using the following IC. https://www.yamar.com/datasheet/DS-SIG60.pdf My design is the same as the example circuit in the datasheet of the chip. Th...
A full wave rectifier converts a sine wave to DC pulsed signal of double frequency. Is there a circuit which does the reverse process?
DC offsets in hundreds of mV from different grounds may be coming from either the floating ground or the PE earth. The latter may be from rectified AC line filter noise shunted to PE. The former m...
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 ...
