Design an amplifier to sense open-circuit output voltage from a transducer and provide proportional current through a load resistor. The series resistance of the transducer is a range between 1 kOhms and 10 kOhms. The load resistance is a range between 1 kOhms and 10 kOhms. The change in load current in response to change in these resistance values is not more than 10%. For a nominal transducer output voltage of 10mV, the current through the load resistor is at least 1mA.
