D 7.12 Consider the CE amplifier circuit of Fig. 7.6 when operated with a dc supply VCC = +3 V. You want to find the point at which the transistor should be biased; that is, the value of VCE so that the output sine-wave signal vce resulting from an input sine-wave signal vbe of 5-mV peak amplitude has the maximum possible magnitude. What is the peak amplitude of the output sine wave and the value of the gain obtained? Assume linear operation around the bias point. (Hint)
0.75 V; 0.45 V; −90 V/V
