    needing values

    salaaam ,
    I have a circuit that i need to find the values for it but i just dont know
    from where to start since i have specefications so if any one can help me i need to finsh it by 2moro
    Its about the CAPACITANCE ADAPTOR FOR MULTIMETERS

    the circiut can be found with the specifications on this page
    http://personal.ee.surrey.ac.uk/Pers...fs/Project.htm
    , then by chosing the project B u will find a component value at the end but the circuit dosent work by using it so our dr said we have to do all the calculations again to find all the values
    if some one could just tell me from where to start
    Thank you for your time

    I think the problem is the chips specified need supply voltage greater than 9 V
    If you refer to its datasheet, it will tell you that supply is +/-15 Volts an does not say "wide supply Range" like LM358 for instance
