Comparators have many uses and its concept is not too hard to grasp. What I don't understand however is how exactly it compares two voltages. How does it know ...Sat, 04 Apr 2026 17:32:00 GMThttps://electronics.stackexchange.com/questions/728134/how-to-calculate-hysteresis-of-a-comparatorHow to explore it The best way to understand this idea is to try implementing hysteresis step by step in your op-amp inverting comparator circuit. Let's simulate each step with a separate schematic so that we get a series of individual partial simulations (frames).Wed, 01 Apr 2026 06:08:00 GMThttps://electronics.stackexchange.com/questions/736636/lm358-comparator-circuitI drew the following circuit using LM358 opamp in order to understand the comparator behavior. I have few questions regarding the circuit below: How should I wire the unused opamp? Will this circuitThu, 02 Apr 2026 19:07:00 GMThttps://electronics.stackexchange.com/questions/164068/can-someone-explain-how-this-transistor-comparator-worksThe circuit is a comparator and can be remarkably useful more or less as shown. I have used a circuit essentially the same as that in production equipment to meet a requirement which was difficult to meet easily and cheaply by other means.Wed, 08 Apr 2026 13:17:00 GMThttps://electronics.stackexchange.com/questions/754236/what-is-the-purpose-of-pulling-up-the-output-of-a-comparator-to-vccThe LM311 device is a comparator with an uncommited transistor output. This means that the output pin needs a pull-up resistor so that it can create a voltage signal and also pin 1 (the emitter)needs to be connected to the lowest supply rail.Sun, 22 Mar 2026 18:09:00 GMThttps://electronics.stackexchange.com/questions/72967/difference-between-differential-op-amp-and-comparatorWhat is the difference between a differential op amp and a comparator? I know a comparator can only give me two values (the supply values). The differential op amp amplifies the difference between...Tue, 07 Apr 2026 06:15:00 GMThttps://electronics.stackexchange.com/questions/33961/what-is-the-difference-between-a-general-comparator-and-a-differential-comparato6 I notice that the LM339 quad comparator comes in 2 different varietys: general-purpose and differential. Besides a big difference in price, what is the difference between the two? Specifically, I want to use it in a slow-changing (as in whole minutes before crossings) single-supply (12v) circuit that needs to output very close to 0 for Vsat-.Mon, 06 Apr 2026 07:21:00 GMThttps://electronics.stackexchange.com/questions/662442/comparator-with-hysteresis-what-resistors-go-whereThe comparator does it during the transition with the help of the positive feedback. What positive feedback is This is positive feedback "out of control" or as they call it, "self-reinforcing positive feedback". Note that there is positive feedback for an extremely short time, only during the transition.Sun, 29 Mar 2026 20:59:00 GMThttps://electronics.stackexchange.com/questions/687349/simulating-cmos-comparator-on-cadence-virtuosoI am trying to simulate the following cmos comparator circuit using cadence virtuoso spectre. Here's my schematic on cadence: I am using the following test bench to simulate the circuit with Ibias...Wed, 01 Apr 2026 20:20:00 GMThttps://electronics.stackexchange.com/questions/718952/i-need-help-to-identify-the-negative-feedback-loop-in-a-hysteresis-comparatorCan anyone help me identify where the negative feedback path is? It's not really feedback in the conventional sense of amplifiers, as a comparator is an amplifier on steroids with a very high gain and a fast switching capability, they are more designed to switch from one state to the next than have a linear region like an opamp.Thu, 02 Apr 2026 20:48:00 GMT
