... are used to transfer heat to other layers of the PCB. Grounding In order to minimize the effects of ground bounce and offset issues, it is important to have a low impedance singlepoint ground, known as a star ground, located very close to the device. By making the connection between the exposed ther ...

... The capability of providing multiple supply voltages is the key for dynamic voltage frequency scaling (DVFS) [1] to success. Typically, a switching dc-dc converter [2] is used to serve the objective. The power efficiency of the switching dcdc converters can be as high as 95%. However, the required l ...

... Three things happen when VGS = 0 and VDS is increased from 0 to a more positive voltage: • The depletion region between p-gate and n-channel increases as electrons from n-channel combine with holes from p-gate. • Increasing the depletion region, decreases the size of the n-channel which increases th ...

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.
