7V. The gain can be calculated using the formula: Gain = Vout / Vin In this case, Vin ranges from 0V-90mV and Vout ranges from 0V-2.7V. Therefore, the gain required is: Gain = (2.7V - 0V) / (90mV - 0V) = 30 Show more…

5.42. We wish to design the degenerated stage of Fig. 5.137 for a voltage gain of 10 with Q1 operating at the edge of saturation. Calculate the bias current and the value of RC if β = 100, IS = 5 × 10^-16 A, and VA = ∞. Calculate the input impedance of the circuit. VCC = 2.5 V, RC = 200. Figure 5.137.

Design the bias circuit of the CE amplifier given in the below figure (Figure 2). Let the current through Re is 50 mA, Vcc = +10V, and β = 150. Figure 2 Find the values of resistors (Re, Rb, and Rc) required to achieve a collector current of 0.5 mA. Compute the transistor amplifier gain (Av) and the small-signal output voltage (Vce) if the early voltage is 100 V and v = -0.25 cos(5000t) V. (Hint: You can use the Thumb rule for solving this problem)
