 For the circuit below, find the input pole (in   rad/s ) using Miller's theorem. Assume that   r_o  is infinity and neglect parasitic capacitances. The current source biasing Q2 transistor is ideal. Assume   g_m  and   r_{\pi}  for Q1 is known.

Answer

\omega_{pi} = \frac{1}{(R_C || r_{\pi})	imes C_F(1 + g_m R_B)}

Answer

\omega_{pi} = \frac{RC}{(R_C || r_{\pi})	imes C_F(1 + g_m R_B)}

Answer

\omega_{pi} = \frac{1}{(R_B || r_{\pi})	imes C_F(1 + g_m R_C)}

Answer

\omega_{pi} = \frac{1}{(R_C + r_{\pi})	imes C_F(1 + g_m R_B)}

Answer

\omega_{pi} = \frac{1}{(R_B + r_{\pi})	imes C_F(1 + g_m R_C)}
