Unformatted text preview: f ect can be neglected, i.e., V A = . Making use of the results of Problem 1, label the branch currents and derive the equation for the output current I O . (b) Aside from the di f erence in the equation for I O , what is the major di f erence between the Wilson mirror and the two-BJT current mirror? Make use of the answer for Problem 1 to solve for I C 2 . I REF = I O + I O / 1 + 2 / = I O = I REF 1 + 1 / 1 + 2 / The output resistance is much higher than for the two-BJT current mirror. This is caused by a positive feedback e f ect. 1...
