Patent ID: 8830011

Claim:
A band-pass filter, comprising: an input node coupled to receive an oscillating input signal; an output node; a first LC resonator coupled to a first node coupled between the input node and the output node and to a first power supply node coupled to provide a first voltage, the first LC resonator including: a first capacitor, and a first inductor coupled in series with the first capacitor, a second LC resonator coupled in parallel with the first LC resonator and coupled to a second node coupled between the input node and the output node, the second LC resonator including: a second capacitor, and a second inductor disposed in series with the second capacitor; wherein the output node is coupled to output a filtered response signal that includes at least one zero based on the oscillating input signal and the first LC resonator, and wherein the first and second inductors are disposed at a distance from one another on a semiconductor substrate such that the first and second inductors are inductively coupled together.
