While input offset voltage is technically noise in the sense that it is something unwanted added to the signal, it is not included in opamp noise specs as far as I have seen. Think of the "noise" ...
I largely agree with Olin Lathrop's answer. However, I think questions should be on-topic also if the trends have no direct technical motivations, on condition that the reasons can be backed by ha...
I was looking at the video of the Tesla Model 3 motor controller(400VDC, 500A) disassembly and noticed a resistor network as in the picture below. They are 2k resistors(SMD code 202). See the pic...
You can predictably generate a voltage with a R-2R ladder or a Rn^2 selector and then use a commodity V-I industrial converter interface to generate the current loop the customer desires. You cann...
Simple filters don't cause a fixed ratio change in amplitude (dB) for a fixed change in linear frequency (Hz). Making the amplitude change by -0.1 dB/Hz would be very difficult. This could be don...
It depends on whther the stages are buffered, or not. If they are buffered then it's more simple, because an RC lowpass has the transfer function: $$H_1(s)=\dfrac{\dfrac{1}{RC}}{s+\dfrac{1}{RC}}=\...
Firstly, is this calculation for power dissipation correct? P = (I2 * R) + (I * V * (t_on+t_off)/2 * f) = 0.517 W Not completely. There are two separate parts that need to be considered. I2RDSO...
If you're really sure the symptom appeared right after the static discharge, then something in the front end of the amplifier may have gotten damaged. However, that sounds rather far fetched. Sco...
The expansion of the conductors is the least of your problems. The real issue is the effect of excessive temperature on the insulators. The plastic in the cable has three electrical functions: T...
I'm not going to get into rigorous analysis. My perception is that you're getting hung up on details and forgetting to think what the overall circuit is doing and how it works. I'll therefore sti...
It seems your main question is why all the comments to your question about reactance were deleted. I deleted them because they were no longer relevant. They pointed out problems with the question...
Anti-Aliasing filter depends on the following parameters; Signal BW Sampling Rate Sampling duration and thus BW of sample LPF attenuation of alias spectrum above 1. From your SNR spec or dy...
I'm not sure what you mean by the "Re" model, but ultimately the transistor does a certain thing regardless of what label we put on the circuit it is in. For a NPN like you're modeling, you will h...
"React" implies a response to an "event". For an inductor, the "event" is a change in current, $\frac{di}{dt}$ For a capacitor, the "event" is a change in voltage, $\frac{dv}{dt}$ $$$$ So, ...
It seems like you did the reduction to a Thevenin source mostly right, although the final value is a bit off. The original circuit we want to reduce to a Thevenin source is: First we reduce V1,...
I'd rather use the AD4111 as a high-side current sensor, instead of creating an "inverter" which would generate an equal and opposite current. Each current input of the AD4111 (IINx+ and IINx-) is...
The 45° routing makes it easier to route multiple parallel traces across the PCB - I would say that's the main reason why they are so popular. Whereas 90° turns of multiple parallel traces next to ...
If you put the Fat load-dump TVS downstream of the reverse-polarity protection MOSFET [1], then the load dump current would have to flow through the MOSFET. The MOSFET would have to be rated for t...
Using a P FET for polarity protection like this means that in case you flip + and -, the gate will be inactive, meaning that GND which is now connected to drain will get disconnected - no current w...
I have a solar panel rated for 6V open-circuit and up to 150mA. I would like to connect this to an SPV1040 or similar buck-boost converter with MPPT functionality to be able to charge a 3.6V batter...
Hello, I am trying to use a CD4047 in monostable, positive-edge trigger mode: I am not skilled enough to make out what the output, i.e. pin 10, should be when pin 8, the input, is held at 0V (...
Lets say I power an oscillator by a non-rechargable battery. Lets imagine a generic design with LC-circuit and negative resistance created by some transistor circuit. To me it seems that at certai...
What does it mean for signals to have impedance? I expect that what it means is that a particular signal source has an effective series resistance (for a voltage source) or, an effective paral...
What does it mean for signals to have impedance? To me, impedance is kinda like an "extended resistance" that also includes phase shift $$Z = R + jX $$It makes sense to me that components like cap...
