A current mirror is used to emulate an ideal current source. It is used to bias a circuit or serve as a load. Excerpt from PSpice on-line reference manual: DC Currents [Vt = thermal voltage, kT/q] Ig = gate current = 0 the resistance is found based upon the relation RN = VAC /IAC.

SPICE is a general-purpose circuit simulation program for nonlinear dc, nonlinear transient, and linear ac analyses. Circuits may contain resistors, capacitors, inductors, mutual inductors, independent voltage and current sources, four types of dependent sources, lossless and lossy transmission lines (two separate implementations), switches, uniform distributed RC lines, and Engineering Electrical Engineering Electrical Engineering questions and answers PSPICE MULTISIM 10.7 Find the average power delivered by the ideal current source in the circuit in Fig. P10.70 if ig = 40cos 1250t mA. Figure P10.7 5 k2 8 H 80 nF Example inverting op-amp circuit. To simulate an ideal operational amplifier in SPICE, we use a voltage-dependent voltage source as a differential amplifier with extremely high gain. The " e " card sets up the dependent voltage source with four nodes, 3 and 0 for voltage output, and 1 and 0 for voltage input. To transform the circuit, change the current source to a voltage source and move R so that it's connected in series rather than in parallel. When you use the constraint equation vs = isR to find the source voltage, remember that R is the resistor you moved. Circuit B is a series circuit where all the devices share the same current.

To analyse the circuits we can apply a simple voltage and current divider techniques by using these transformations. This source transformation method can also be used to convert a circuit from […] Source transformation methods are used for circuit simplification to modify the complex circuits by transforming independent current sources into independent voltage sources and vice-versa.
