... The most common application is to increase the noise immunity of a circuit. In a comparator, there is only a signal threshold voltage. If the input is noisy, then the output will bounce if the noise causes the input to cross the threshold. In a Schmitt Trigger, though, once the output transitions (s ...

... coulomb per second past a given point in the circuit. An ammeter measures the flow of charge (current) through a wire or electrical device. Two important facts about ammeters are: 1. Ammeters have very low resistance to the current so that, when placed in a circuit, the current is not impeded. 2. Am ...

Current mirror

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 is a current-controlled current source (CCCS). The current mirror is used to provide bias currents and active loads to circuits. It can also be used to model a more realistic current source (since ideal current sources don't exist).The circuit topology covered here is one that appears in many monolithic ICs. It is a Widlar mirror without an emitter degeneration resistor in the follower (output) transistor. This topology can only be done in an IC as the matching has to be extremely close and cannot be achieved with discretes.Another topology is the Wilson mirror. The Wilson mirror solves the Early effect voltage problem in his design.
