The signal source in Figure P6.18 is u= 5 sin wt mV. The transistor parameters are ß = 120 and V4 = x. (a) (1) Design the circuit such that Icq = 0.25 mA and VCEQ = 3 V. (i) Find the small-signal voltage gain Au = uo/us. (ii) Find uolt. (b) Repeat part (a) for Rs = 0. v* = +5 V RC Rs = 2.5 k2, R=5 k2 CE RE V = -5 V Figure P6.18 www The signal source in Figure P6.18 is u= 5 sin wt mV. The transistor parameters are ß = 120 and V4 = x.
