... Voltage is the difference in electric potential between two points. To express this difference, we label a voltage with a “+” and “-” : b a 1.5V Here, V1 is the potential at “a” minus + V1 the potential at “b”, which is -1.5 V. Current is the flow of positive charge. Current has a value and a direct ...

... The input bias current (IB) is a non-ideal, real-life parameter that affects all op amps. IB can generate a somewhat significant offset voltage. This offset voltage is created by IB when flowing through the negative feedback resistor RF. If IB is 250 nA (worst case), and RF is 100 kΩ, the correspond ...

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.
