Abstract
The invention discloses a decoupling capacitor circuit, comprising a plurality of coupled deep trench capacitors connected in series and a plurality of push-pull circuits. The decoupling capacitor circuit controls the voltage across each deep trench capacitor via the push-pull circuit so that it will not be influenced by the defect (leakage current) of the deep trench capacitor or the bias voltage of the parasitic devices.
