... There is a trick to this last calculation. We know that any time output is twice the amount of input, that the gain is 3 decibels. Likewise, we know that any time the output is one half the input, the loss is 3 decibels - expressed as “minus” 3 decibels. So, when you have one fourth the output that ...

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.
