The designer of the amplifier in Example 7.8 decides to lower the bias current to half
Chapter 7, Problem 7.22(choose chapter or problem)
The designer of the amplifier in Example 7.8 decides to lower the bias current to half its original value in order to raise the input resistance and hence increase the fraction of vsig that appears at the input of the amplifier proper. In an attempt to maintain the voltage gain, the designer decides to double the value of RC. For the new design, determine Rin, Av o, Ro, Av , and Gv . If the peak amplitude of v is to be limited to 5 mV, what are the corresponding values of vsig and vo (with the load connected)?
