A BJT cascode amplifier uses transistors for which β =100, VA =100 V, Ft =1 GHz, andCμ =0.1 pF. It operates at a bias current of 0.1 mA between a source with Rsig =rπ and a load RL =βro. Let CL =Ccs =0, and rx =0. Find the overall voltage gain at dc. By evaluating the various components of τH show that the pole introduced at the output mode is dominant. Find its frequency and hence an estimate of fH and ft .
