Multi-Band Equalizers - A simplified explanation of the abstract

• This abstract for appeared for US patent application number 18334893 Titled 'Multi-Band Equalizers'

Simplified Explanation

The abstract describes the concept of on-chip multi-band equalizers used to adjust the signal strength of a receiver that receives multi-band frequency signals. These equalizers consist of multiple tapped LC resonators connected in series. The tapped resonators can be either capacitive or inductive, and the frequency and gain of the desired frequency bands can be adjusted by tuning the capacitances of programmable capacitors or selecting the tapped-out terminals of the inductors. The multi-band equalizer is typically connected to a signal node, such as between two amplifiers in the receiver.

Original Abstract Submitted

On-chip multi-band equalizers for adjusting signal strength for a receiver receiving multi-band frequency signals are provided. An example multi-band equalizer comprises multiple series connected tapped LC resonators. The tapped LC resonator may be capacitive tapping or inductive tapping, where both frequency and gain of the frequency bands of interest may be programmed by tuning the capacitances of the programmable capacitors and/or selecting the tapped-out terminals of the inductors. The multi-band equalizer may be connected to a signal node, for instance between two amplifiers in the receiver.
