voltage - How exactly does a comparator work? - Electrical …
Apr 11, 2015 · The core of a comparator is usually a long-tailed pair. This is an arrangement of transistors which amplifies the difference between two signals, presents a high input …
Can someone explain how this transistor comparator works?
Apr 10, 2015 · Thus, a comparator consists of a subtractor and an amplifier. Conceptual circuit. Let's first build a conceptual comparator to figure out the idea. Series voltage subtractor. The …
operational amplifier - LM358 comparator circuit - Electrical ...
Jan 21, 2025 · For comparator applications, it's best to use a comparator. LM358 (an op-amp) and LM393 (a comparator) cost about the same, but the LM393 outperforms the 358 opamp in …
How can I make an ideal comparator in LTspice?
Oct 1, 2017 · This component looks like an open switch (OFF) when the differential input voltage is greater than the threshold (Vt) and like a closed switch (ON) when the input is less than the …
How to deal with strobe and balance pins of this comparator for …
If the inverting input voltage is 3.000000V, and the non-inverting input voltage is 3.000001V, an ideal comparator will output 'high'. However, non-ideal comparators may have a mis-match, …
Understanding this comparator circuit for AC voltage protection
Jul 15, 2019 · So, the comparator will see a sine wave which matches the line voltage at the zero crossing, but will be clamped between -0.35V and 0.35V. This zero crossing is required to …
What is the difference between a general comparator and a …
Jun 15, 2012 · The term "differential comparator" essentially means "a device that compares and acts on the difference between two variables" so for a comparator to not be differential is, in …
Why can't a single-supply comparator handle negative inputs?
Aug 9, 2020 · A comparator with R-R outputs will get close to zero volts, but nothing is perfect. I would suggest using bi-polar supplies, but diodes are needed to prevent negative outputs. …
Difference between differential op amp and comparator
Oct 9, 2015 · The comparator is optimised to switch cleanly and may have less attention paid to linearity and stability under linear conditions. \$\endgroup\$ – Russell McMahon ♦ Commented …
schmitt trigger - How to calculate hysteresis of a comparator ...
Oct 16, 2024 · The comparator input impedance is high and can be ignored unless you want to take the bias current into account. (It's typically not very significant.) Of course there are …
