1.61 It is required to design an amplifier to sense the open-circuit output voltage of a transducer and to provide a proportional current through a load resistor. The equivalent source resistance of the transducer is specified to vary in the range of 1 k to 10 k. Also, the load resistance is known to vary in the range of 1 k to 10 k. The change in the current supplied to the load corresponding to the specified change in Rs is to be 10% at most. Similarly, the change in load current corresponding to the specified change in RL is to be 10% at most. Also, for a nominal transducer open-circuit output voltage of 10 mV, the amplifier is required to provide a minimum of 1 mA current through the load. What type of amplifier is required? Sketch the amplifier circuit model, and specify values for its parameters. For Ri and Ro, specify values in the form 1×10m .
