... This component is a 4-bit nonlinear digital-analog converter. Three of these bits have a small bias (that is, they vary the output by only a small amount) and are directly under the control of the OBDH system through the HV set pins. The last bit has a large bias and is tied to the HV on pin. The th ...

... current limiting has no effect during turn–off. Turn–on, however, is another matter. Spikes that are routinely seen at turn–on can easily produce false trips that interfere with proper circuit operation. Fortunately, filtering is relatively easy. Due to the limited duration of the noise, a simple si ...

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.
