... In a 4-wire three phase system, the fundamental currents at any instant will always add up to zero in the neutral. However, the third harmonic of each phase is always in phase with those of the other two phases. As a result, rather than canceling each other (as is the case with the fundamental), the ...

... It is important to properly size this FET relative to the size of the HEMT being biased, in terms of RDSON, RTH, and VDSMAX. In general, smaller gate periphery HEMTs can be switched with smaller- and less expensive – MOSFETs. Specifically, RDSON is selected to keep the voltage drop across the switch ...

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.
