... 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.
