    Consider the circuit. The opamp is ideal.

    Find the transfer function H(w)=Vo(w)/Vs(w).

    Find the magnitude and phase of H(w).

    Plot the magnitude (dB) and phase of H(w) on a Bode plot (vs log w).

    What type of filter is this?

    We analyze the circuit in the s-domain, where

    In the s-domain, the impedance of the capacitor is .
    For the ideal opamp, at the negative input node of the opamp, applying KCL, we have

    At the positive node,

    Then VN = VP, so

    Then the ...
