Comparator Vs Comparable In Java 8 This way the comparator will have a constant well defined internal state and output state Leaving both inputs open won t cause as much noise amplification as it does in op amps and other comparators because this one has an open collector output
Java 8 Comparator LTSPICE DOES have the equivalent of an ideal comparator It is the Voltage Controlled Switch listed as SW in the top level symbol list 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 threshold

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 simplest way to subtract two input voltages Vin1 and Vin2 is to connect their two sources in series in opposite directions I ve setup a simple circuit with an LM358 configured as a comparator the ground rail and supply connections are off screen Schematic Breadboard in case I wired something wrong Measured valu
begingroup HariKrishna Um the circuit to cancel the offset is another voltage source connected in series with either Vin1 or Vin2 See adding voltage sources to model offset is a game that s easy to exploit and makes it easy to 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 comparator applications LM358 is a very slow comparator LM393 is a much faster comparator and a very poor op amp

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 impedance especially if MOSFET and usually somewhat rejects any common voltage In circuit terms the long tailed pair is close to the input of the comparator By contrast in a comparator application linearity is of no concern and neither is mirror current disparity Q7 also keeps the collector of Q6 clamped to a maximum of 0 7V It might seem that this will have the same effect as your error of clamping that potential with a diode but you must remember that Q7 base current is a tiny fraction of Q6 mirror current half
