Why buy extra books when you can get all the homework help you need in one place? Remember to use a factor of safety in your design. Choose relatively low values of resistors but ones for which the input current from each input signal source does not exceed 50 μA for 1-V input signals. Specifically, a voltage divider R5 , R6 connected across the output feeds a fraction β of the output, that is, a voltage βv O , back to the positive-input terminal of the op amp through a resistor R. Disregarding how biasing is to be done, what is the largest possible voltage gain available for a signal source connected directly to the base and a very-high-resistance load? For the purpose of these initial designs, assume no load. Neglect the effect of resistor tolerances on Ad. What are the values of β and the incremental β or β ac that apply?

Also, for a nominal short-circuit output current of the transducer of 10 μA, the amplifier is required to provide a minimum of 1 mA through the load. Assume that R5 and R6 are much smaller than R so that the current through R is much lower than the current in the voltage divider, with the result that vId Figure P2.
