Determine Balancing Current for the LTC3305 Lead
Determine Balancing Current for the LTC3305 Lead

... Once the Curie point is reached, current is limited by the resistance of the PTC. In this way, the PTC acts as a constant power device, limiting the pass-through current as the VDIFF increases. Predicting the balancing current of the LTC3305 involves plotting a current-voltage curve for the total ci ...

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.
