摘要:
Off-chip LC circuit for lowest ground and VDD impedance for power amplifier. A novel approach is made by which a chip to PCB (Printer Circuit Board) interface may be made such that the ground and VDD potential levels are effectively brought onto the die of the chip such that a true ground potential is maintained within the chip. This off-chip LC circuit operates cooperatively with an on-chip decoupling capacitor to reduce the overall effective inductance of the bond wires employed to bring signal and voltage levels from the die to the chip exterior. This circuit ensures a relatively low impedance for a PA (Power Amplifier) that is implemented within chip thereby providing for improved performance.
