The input current for a buck power converter is discontinuous due to
The input current for a buck power converter is discontinuous due to

... The inductor current flows into the output capacitor and load resistor combination. The average current flowing in the output capacitor is always zero so the buck converter load current is the average of the inductor current. When the load current is decreased below a critical level, i.e. half the i ...

... energy provided by the power supply is absorbed by the resistors. In a multi-loop circuit, the values of the resistors and the power supplies are known. It is necessary to determine how many independent currents are in the circuit, to label them and then to assign a direction to each current. Applic ...

... The on-board network in a modern automobile has a large number of appliances and loads. Rapid changes in load lead to large voltage variations. For example the 12 V battery voltage drops for about 100 ms below 5V while the starter converts a lot of energy during cranking. Therefore, conventional vol ...

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.
