Oh No! I Have to Design a PA

... HBTs – different HBTs can be used for different purposes – there are trade-offs. Scalability is a good approach to provide designers with the right tool for the job. FETs – the requirements on the FET depends on how it is used. For bias circuit, FET above Emitter is okay. For higher frequency/power ...

... There are diodes from NC/NO to the supplies in addition to the SCRs. A resistance in series with each of these diodes limits the current into the supplies during an ESD strike. The diodes protect these terminals from overvoltages that are not a result of ESD strikes. These diodes also protect the de ...

... Monostable operation is initiated when TRIG voltage falls below the trigger threshold. Once initiated, the sequence ends only if TRIG is high for at least 10μs before the end of the timing interval. When the trigger is grounded, the comparator storage time can be as long as 10μs, which limits the mi ...

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.
