You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can d… ...

These circuits are used as building blocks for designing a high-temperature SiC low-side over current protection circuit. The over current protection circuit is used in the protection circuitry of a ...

Performance can be improved by adding a hysteresis voltage to the basic circuit, reducing its sensitivity to noise. Figure 4: Basic use of an op amp as a comparator (left) and an improved circuit with ...

This paper describes a high temperature voltage comparator and an operational amplifier (op-amp) in a 1.2-μm silicon carbide (SiC) CMOS process. These circuits are used as building blocks for ...

Over-zero voltage comparator: a typical amplitude comparison circuit with the circuit diagram and transmission characteristic curve shown in the figure.
