Not to be confused with Dynamic loading.''An active load or dynamic load is a component or a circuit that functions as a current-stable nonlinear resistor.==Circuit design==In circuit design, an active load is a circuit component made up of ''active devices'', such as transistors, intended to present a high small-signal impedance yet not requiring a large DC voltage drop, as would occur if a large resistor were used instead. Such large AC load impedances may be desirable, for example, to increase the AC gain of some types of amplifier. Most commonly the active load is the output part of a current mirror and is represented in an idealized manner as a current source. Usually, it is only a ''constant-current resistor'' that is a part of the whole current source including a ''constant voltage source'' as well (the power supply VCC on the figures below). :''"Dynamic load" redirects here.
