High efficiency half-cross-coupled decoupling capacitor

A method for suppressing power supply noise, comprising:

• connecting a first source and a first body of a first p-channel field effect transistor (PFET) to a voltage supply;
• connecting a second source and a second body of an n-channel field effect transistor (NFET) to ground;
• connecting a first drain of the first PFET to a first gate of the NFET;
• connecting a second drain of the NFET to a second gate of the first PFET;
• connecting a third drain, a third source, and a third body of a second PFET to the voltage supply;
• and
• connecting a third gate of the second PFET to the second gate of the first PFET.
