Find the low-frequency gain am

Reference no: EM131018831

Consider a bipolar cascode amplifier biased at a current of 1 mA. The transistors used have β = 100, ro = 100 KΩ , Cπ =10 pF, Cμ =2 pF, Ccs =0, and rx =50Ω. The amplifier is fed with a signal source having Rsig = 5 kΩ. The load resistance RL = 2 kΩ . Find the low-frequency gain AM, and estimate the value of the 3-dB frequency fH.
