BASIC CONFIGURATIONS 7.81 PLEASE SHOW ALL WORK WHEN SOLVING THIS PROBLEM ..THANKS ! 7.81 ACB -0.2 mA with R.-RL= 10 k and is driven by a signal source with Rsig 0.5 k2. Find the overall voltage gain G. If the maximum signal amplitude of the voltage between base and emitter is limited to 10 mV amplifier is biased at IE Solution By using given data, gm= Ic/Vt = 7.72 mA/V draw signal model for that data, for the comman base transister. for voltage gain, used KVL, Here, Vo= Vpi, Vo-Vi / 0.5 + Vo/(10||10) + gmVo = 0; by solving this, Vo/Vi = 0.332 voltage gain = 0.332 Now for amplitudes for Vo, used 1 ampiter Vtest current and KCL law, Vtest = Vo = 10.6 V..
