WebJan 25, 2024 · In practice, current mirrors are most often used as an active load in the input stages of op amps and comparators. A current mirror has a lower voltage drop than reasonable emitter resistors, and allows larger amplification. (Its primary purpose is not really to mirror the current.) One of the simplest devices is the LM339 comparator: WebOct 9, 2024 · Typically, in power supply ICs (i.e. TI’s Simple Switcher) the only access you have to change V out is the inverting pin that controls the feedback (FB in Figure 1). A very easy method to control FB is to replace R b with a controllable current source, and the simplest and cheapest way to do that is using a current mirror (Figure 2).
