What change should I make in my Lead Compensator circuit below to reduce the DC response? Vin be sine wave with variable frequency

AC response

As C1 gets smaller a 6 dB change in the AC response occurs at a higher frequency. At high frequencies, the gain is unity or 0 dB. At low frequencies, the gain is 50% or -6 dB.

reduce the DC response?

If you want to reduce the DC response you can make R2 smaller or R1 bigger.
