1.59 It is required to design an amplifier to sense the open-circuit output voltage of a transducer and to provide a proportional voltage across 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 varies in the range of 1 k to 10 k. The change in load voltage corresponding to the specified change in Rs should be 10% at most. Similarly, the change in load voltage corresponding to the specified change in RL should be limited to 10%. Also, corresponding to a 10-mV transducer open-circuit output voltage, the amplifier should provide a minimum of 1 V across the load. What type of amplifier is required? Sketch its circuit model, and specify the values of its parameters. Specify appropriate values for Ri and Ro of the form 1×10m .
