A current mirror is a circuit designed to copy a current through one active device by controlling the current in another active device of a circuit, keeping the output current constant regardless of loading. The current being copied can be, and sometimes is, a varying signal current. Conceptually, an ideal current mirror is simply an ideal inverting current amplifier that reverses the current direction as well. Or it can consist of a current-controlled current source CCCS.

Before us opened up, in mirage, Towns constructed out of wonder, Mint leaves spread themselves beneath our feet, Birds came on the journey with us, Fish leapt in greeting from the river, And the sky unfurled above First Dates -A. Conceptually, an ideal current mirror is simply an ideal current amplifier with a gain of -1. In Chapter 8 we explored the transistor and you should recall that the BJT device is a current amplifier of sorts current controlled current source in that the collector current is β times the base current. The use of feedback and the current to voltage relationship of two terminal elements such as a resistor are most often used when manipulating currents as signals. Because in a current mirror the input and output are currents, it is easier to convert the input to a voltage first and then convert a voltage back to a current at the output. 0 is a current mirror, a device that uses the current in one half of the circuit to control the current flow in the other half. The current is the same in both halves. The switch on the left changes the current flow in the left half, which is mirrored in the right half. The current through it is set by the resistor network below it. Wiring the base to the collector ensures that the base current can flow, so the transistor can stay in the active mode. Since Q1's base is wired to Q2's, they are at the same voltage, so Q2's emitter-base junction must have the same amount of current flowing through it. It acts like a diode, so the current is determined by the voltage across it. The ZDS1009 current mirror has been developed for high side, current sense plus level translation applications. Typical applications are including battery charge management, DC motor control and over current monitoring. It is of particular interest for current sense applications for feedback purposes in fast battery chargers for Li-Ion cell based systems. Find Parts. Export all parts. 1 shows the basic npn current mirror. For its analysis, we assume identical transistors and neglect the Early eect, i. we assume VA . This makes the saturation current IS and current gain β independent of the collector-base voltage VCE. The input current to the mirror is labeled IREF. This current might come from a resistor connected to the positive rail or a current source realized with a transistor or another current mirror. Figure 3 shows the basic current mirror with a third transistor added. The collector of Q3 must be connected to a positive reference voltage, e. the positive supply rail, which biases it in the active.

I was reading about current mirrors and while a current mirror built with NPN transistors was easy to understand, the direction of current flow confuses me when you switch to PNPs. In the attachment you can see a PNP current mirror circuit from AoE. I'm not sure if my understanding of PNPs is flawed, but it seems like the current would have to flow backwards to satisfy that statement, at least. A current mirror essentially copies a current injected into one transistor Q1 in this case and creates a current source into the collector of Q2 in this case. While this circuit doesn't do much on its own, it's a core part of lots of analog amplifier circuits, as it can ensure that two parts of the signal chain have the same bias current running through them. This is also an example of a translinear circuit, as Q1 acts as a diode, converting a current to a logarithmically-related voltage. That voltage is applied to the base of Q2, which acts as an exponentially-rel
