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 do that with ...

Why low-side current sensing is still widely used. Why a precision preamplifier is critical to low-side current-sensing ...

One of the simplest ways to implement an SR flip-flop is using NAND gates. Above, you can see the basic circuit diagram of an SR flip-flop made using a combination of NAND gates. You can use any NAND ...
