Abstract
A discrete field coupled capacitor with a cross-connected capacitor-pair, such as for use as a discrete bypass capacitor. The FCC includes a first port with first and second terminals, and a second port with third and fourth terminals. A first capacitor structure is connected between the first and second terminals, and a second capacitor structure connected between the third and fourth terminals. A cross-connect structure includes a first cross-connection to connect the first terminal to the third terminal, and a second cross-connection to connect the second terminal to the fourth terminal, to cross-connect the first and second capacitor structures. The capacitor structures have respective parasitic ESL, and can be disposed in proximity to effect a pre-defined ESL field coupling with reverse phasing to reduce parasitic ESL. The FCC can be constructed as a PCB or monolithic device. In a PCB four-layer construction, the cross-connections can be formed on respective mid-layers.
