Abstract
A decoupling capacitor includes a pair of MOS capacitors formed in wells of opposite plurality. Each MOS capacitor has a set of well-ties and a high-dose implant, allowing high frequency performance under accumulation or depletion biasing. The top conductor of each MOS capacitor is electrically coupled to the well-ties of the other MOS capacitor and biased consistently with logic transistor wells. The well-ties and/or the high-dose implants of the MOS capacitors exhibit asymmetry with respect to their dopant polarities.
