Abstract
A method for implementing an inductor-capacitor filter in an integrated circuit. Embodiments of the invention implement a 5-pole LC low-pass filter suitable for incorporation in wireless applications necessitating compact layouts. Inductors are formed in an IC as concentric coils on metallization layers, the concentric coils providing a negative coupling coefficient between the inductors. The invention provides programmable frequency response characteristics, enabling the transmission of high-frequency base band information while attenuating carrier RF frequencies.
