1.62 It is required to design an amplifier to sense the short-circuit output current 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. Similarly, the load resistance is known to vary in the range of 1 k to 10 k. The change in load voltage corresponding to the specified change in R s should be 10% at most. Similarly, the change in load voltage corresponding to the specified change in RL is to be limited to 10%. Also, for a nominal transducer short-circuit output current of 10 μA, the amplifier is required to provide a minimum voltage across the load of 1 V. What type of amplifier is required? Sketch its circuit model, and specify the values of the model parameters. For Ri and Ro, specify appropriate values in the form 1×10m
