You are making this too complicated. The only thing that matters is the percentage mismatch between any two clocks on a CAN bus. You seem to imply that you are willing to guarantee the -10 °C to ...
In the circuit below, I am applying a $3.3Vpp$, $63kHz$, 50% Duty Cycle, PWM input signal at the gate of the mosfet and I am expecting to see a similar waveform with different amplitude at the LED...
I've created the category and enabled the Article post type (only). It uses the same tag set as Q&A. If you want me to change either of those, let me know. Please let me know what you'd like ...
I'm using a variable duty cycle square-wave oscillator to drive a half-bridge MOSFET pair like this. Upper MOSFET is P-channel type, lower MOSFET is N-channel type: - And, I think I'm getting shoo...
To avoid shoot-through you should ensure that the active-low P-channel MOSFET gate drive voltage never overlaps with the active-high N-channel MOSFET gate drive voltage. With an inverter driving th...
Why do the Darlington or Sziklai configurations need complementary transistors? They don't. In fact, it's usually not even desirable. However, before we get too far, let's make it clear what we ar...
When switching a relay there should be a flyback diode. It could be just a diode or diode with resistor in series. I understand there is a difference in the speed of relay switch-off. But what is t...
I understand that some applications require NPN-PNP pairs with identical electrical characteristics. But I would like to understand why.
Here is the circuit in question, with the component designators changed to make them easier to write: To understand this circuit, try building it up in pieces. First, let's only include R1 and R2....
I've built a non-inverting op-amp amplifier with a gain of 101 using this circuit: - My input is 10 mV DC and I expected to measure 1.01 volts at the output but I measure 0.81 volts. What has happ...
It's not completely clear, but it seems you are asking about a circuit in a class 1 div 2 location that will drive another circuit in a class 1 div 1 location. The point of the IS barrier is to pre...
How do I calculate the inductance and capacitance out from the barrier to make sure it is less than the sensor values? The output capacitance and inductance from your zener barrier is irrelevant ...
I am designing a PCB that has to have class 1 div 1 associated apparatus (only the outputs to the sensor) certification. Essentially, I am using a boost converter to convert the voltage from a lith...
A couple of problems stick out; one glaring and one a little subtler. Read this in the data sheet: - You have the enable pin connected to your 25 volt output. I'm not saying this is definitely cau...
I don't have a real answer. This is just a suggestion for how to proceed. Look for amplifiers intended to drive 50 Ω cable. Sometimes the term line driver is used, even though that also means ot...
I have had my soldering iron tips degrading at ridiculous rates. Granted, they are not very expensive, but sometimes it takes less than 8 hours of soldering for them to degrade to the point where t...
The 555 timer has a maximum output current rating (for example 250 mA for the NE555, check your 555 version datasheet). So whether or not you have to introduce a mosfet depends on whether your appl...
Coquelicot's answer explains what is going on, so I won't duplicate that. However, one of the sources of confusion is that you are looking at the two waveforms in isolation. Your scope obviously ...
I have a 900MHz radio with a reference design matching network. The radio feeds to a PCB antenna (PCB antenna hasn't been verified with a VNA, and may not be a great match; this is a project to n...
No. You use the right concept whenever you need to use it. There is no preference of "power" over "energy". For example, the energy stored by a cap is equal to ${1\over 2} C V^2$. This is often us...
Power makes sense for steady state conditions. A certain energy will be used over one second. Then the same energy will be used the next second. And the next second. If I told you that such a c...
Small-shop question here. Is there a convenient tool for making the bend shown below, other than a pair of pliers that happens to be just the right size, and is it worth it for qty low 100's? ...
In circuit analysis why always the power has upper hand over energy? One obvious reason: - If we calculate how much power a resistor dissipates we can calculate how hot it will get (knowing i...
We got a copy of the hardware and took a first crack using a lowpass Chebyshev filter at 950MHz (radio transmits up to ~930MHz). On the first pass, we got a .2dBm drop on the fundamental [margin o...
Step 1: Since 3V3_ISO would be LDO driven I would probably add a diode with the anode connected to the LDO output and a cathode connected with the LDO input to prevent the LDO to have output high...
