Millmans Theorem - Wintec Learning
Millmans Theorem - Wintec Learning

... In electrical engineering, Millman's theorem (or the parallel generator theorem) is a method to simplify the solution of a circuit. Specifically, Millman's theorem is used to compute the voltage at the ends of a circuit made up of only branches in parallel. It is named after Jacob Millman, who prove ...

... Pin1 to Pin5 (paralleling the internal 15kΩ resistor). For 6dB effective bass boost: R ≅ 15kΩ, the lowest value for good stable operation is R = 10kΩ if Pin8 is open. If Pin1 and Pin8 are bypassed then R as low as 2kΩ can be used. This restriction is because the amplifier is only compensated for clo ...

... voltage source, V, has a voltage V between its terminals (in the direction indicated by the arrow), no matter what current is flowing in the source. For example, an ideal 5 V source has a voltage of 5 V across its terminals, for currents of 1 mA, 1 A or 1000 A. This behaviour contrasts with a real s ...

... That was a nice simple question requiring only that we use the graph to determine that with 40 mA through the diode there is a 2.0 V drop across it, leaving a 4 V drop across the resistor which needs to have a current of 40 mA flowing through it. Thus R = V/I = 4/40 = 0.1 k = 100  2. In a similar ...

Wilson current mirror



A Wilson current mirror is a three-terminal circuit (Fig. 1) that accepts an input current at the input terminal and provides a ""mirrored"" current source or sink output at the output terminal. The mirrored current is a precise copy of the input current. It may be used as a Wilson current source by applying a constant bias current to the input branch as in Fig. 2. The circuit is named after George R. Wilson, an integrated circuit design engineer who worked for Tektronix. Wilson devised this configuration in 1967 when he and Barrie Gilbert challenged each other to find an improved current mirror overnight that would use only three transistors. Wilson won the challenge.
