Peaking current mirror
WebMay 22, 2024 · Another use for current mirrors is in the application of active loads. Instead of using simple resistors for the collector loads, a current mirror may be used instead. A PNP based current mirror suitable for use as an active load in our previous circuits is shown in Figure \(\PageIndex{16}\). Figure \(\PageIndex{15}\): Current mirror bias. WebA current mirror is a circuit block which functions to produce a copy of the current flowing into or out of an input terminal by replicating the current in an output terminal. An … The current mirror as a load The following figure shows a variation of the emitter …
