Question about current-steering circuit

  1. Jan 25, 2012 #1
    1. The problem statement, all variables and given/known data
    my teacher needs me to design a circuit .. which can control the 5 transistor by the change of the current ... it means that when the different value of current .. the one of the 5 transistor can turn on or turn off .. it is so confused

    can someone give some hit of this question
    2. Relevant equations
    my teacher told me to find some imformation about current source and current mirror .. but i dont think it is related to the current-steering circuit


    3. The attempt at a solution
