Abstract:
1. A method of decoupling electronic devices in an integrated circuit, the method comprising: providing the integrated circuit with a plurality of electronic devices situated on a semiconductor die; providing a self-contained switchable decoupling capacitor (SCSDC) circuit adjacent at least one of the plurality of electronic devices; coupling the SCSDC circuit between first and second power supply interconnects adjacent the at least one of the plurality of electronic devices, the SCSDC circuit including a decoupling capacitor that couples to a switching circuit internal to the SCSDC circuit, the switching circuit being coupled between the first power supply interconnect and the decoupling capacitor, the switching circuit being further coupled between the decoupling capacitor and the second power supply interconnect, wherein the switching circuit operates in a connect mode to connect the decoupling capacitor to the first and second power supply interconnects and in a disconnect mode to disconnect the decoupling capacitor from at least one of the first and second power supply interconnects; thereafter controlling the operation of the SCSDC circuit by:
