In this circuit, a PNP transistor sources current. The base voltage is about ... the PNP circuit with a capacitor and run a transient analysis. Just be sure to set the UIC option on the analysis ...

So if nothing else, today's lesson in circuit analysis will ... you knew about the power source and the number and configuration of the resistors to figure out the current that runs through ...

(Editor’s note: the author was confused between the GPL open-source Qucs ... model various types of circuit behavior, such as DC, AC, transient, and small-signal analysis. Unfortunately there ...

The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...

This article describes the composite current source (CCS) noise modelfor cell-level noise analysis. CCSisa modeling capability ... refers to the problem of propagating a noise bumpthrough a circuit ...

So, a JFET may be a way to make a low-noise current source or voltage regulator. The simplicity of the circuit also means it will respond with low latency to input voltage changes. This transient ...

voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is building a good current source, especially when the ...

The EET allows you to remove impedance elements and dependent sources from a circuit so you can restrict your analysis to a simpler circuit ... such as voltage gain, current gain, or loop gain, and ...
