Abstract
One embodiment of the present invention provides a device for providing a low noise power supply package to an IC in the mid-frequency range of 1 MHz to 3 GHz including installing in said package an array of embedded discrete ceramic capacitors, and optionally planar capacitor layers. A further embodiment provides a device for providing a low noise power supply package to an IC in the mid-frequency range of 1 MHz to 3 GHz including an array of embedded discrete ceramic capacitors with different resonance frequencies, arranged in such a way that the capacitor array's impedance vs frequency curve in the critical mid-frequency range yields impedance values at or below a targeted impedance value.
