Comparator connection with SR latch v2
I removed the inverter and added an extra voltage pulse source which is working as the external reset button. The source resets the SR NOR latch immediately after the start of the simulation and every ...

What is this comparator in the Arduino Uno Revision 3 doing?
That would load the pin significantly if it was configured as an input.
Using half of a dual op-amp as a buffer is a reasonable design choice, when you need the other half elsewhere. Might not be ...

What is this comparator in the Arduino Uno Revision 3 doing?
The LMV358 is an opamp, not a comparator, and that's called the "voltage follower" configuration. It's functioning as a buffer so that SCK isn't loaded directly by the LED.

Comparator as a current detector with shunt resistor v2
To detect two different voltages, you need two comparators. You also will need two separate reference voltages, one for each comparison.
The LM324 is an opamp, not a comparator. If you want to ...

Comparator as a current detector with shunt resistor v2
You can simply add a second op-amp with the appropriate negative 1V reference voltage and 'or' the two outputs with a couple diodes and resistor to -V or GND.

Frequency detector/comparator problem
There are a variety of frequency-to-voltage and voltage-to-frequency ICs, if you want to go down that route.
Another option, if you want to make such a system, would be to use the output of a non-...

Frequency detector/comparator problem
NOTE: In your 2nd and 3rd schematics, components with the same reference designators have different values and do different functions. This is very confusing. Please update your post so the ...

Comparator as a current detector with shunt resistor
Starting with your original schematic here is an example of an over current circuit. In this example R4 (1 Ohm) is the "Shunt" resistor (a.k.a. Sense Resistor). The reference voltage is ...

How does this zero crossing detector circuit work? How can I modify it to work at lower supply voltage?
What is the purpose of R2, R3, and R5 in the zero crossing detector section?
R2 & R3 form a voltage divider from the +12V supply, which sets the threshold voltage for the comparator U1 pin 2. ...

How does this zero crossing detector circuit work? How can I modify it to work at lower supply voltage?
"1. What is the purpose of R2, R3, and R5 in the zero crossing detector section?"
As me, to make an appropriate voltage shift when input is not connected to jack. So ZCD will be in ...

Simulating cmos comparator on cadence virtuoso
You have not biased the comparator properly. An NMOS input pair comparator will need the reference voltage to be higher than VGS(M1)+VDS(M5). Since you've connected the reference to 0V, the comparator ...
