An opamp has an open-loop transfer function given by

                                    A s( ) A0( ) 1 + sτz sτ1( ) 1

Find the transfer function of the closed-loop amplifier, assuming a feedback factor exists. Find approximate equations for the resonant frequency and the Q factor of the denominator of the transfer function of the closed-loop amplifier.
