D *1.56 You are required to design a voltage amplifier to be driven from a signal source having a 5-mV peak amplitude and a source resistance of 10 kΩ to supply a peak output of 2 V across a 1- kΩ load. (a) What is the required voltage gain from the source to the load? (b) If the peak current available from the source is 0.1 µA, what is the smallest input resistance allowed? For the design with this value of Ri, find the overall current gain and power gain. (c) If the amplifier power supply limits the peak value of the output open-circuit voltage to 3 V, what is the largest output resistance allowed? (d) For the design with Ri as in (b) and Ro as in (c), what is the required value of open-circuit voltage gain, , of the amplifier? (e) If, as a possible design option, you are able to increase Ri to the nearest value of the form 1 × 10n Ω and to decrease Ro to the nearest value of the form 1 × 10m Ω, find (i) the input resistance achievable; (ii) the output resistance achievable; and (iii) the open-circuit voltage gain now required to meet the specifications. (a) 400 V/V; (b) 40 k; 2 × 104 A/A; 8 × 106 W/W; (c) 500; (d) 750 V/V; (e) (i) 100 k; (ii) 100 ; (iii) 484 V/V
