Abstract
Devices and methods capable of addressing filter responses are disclosed. For example, a method for compensating a first low-pass filter and a second low-pass filter is disclosed. The method includes injecting a reference tone fand a cutoff tone finto the first low-pass filter, and measuring respective filter responses of the reference tone fand the cutoff tone fwhile changing capacitor codes that control a cutoff frequency of the first low-pass filter until a first capacitor code Iis determined that most accurately causes the first low-pass filter to utilize a desired cutoff frequency f, performing a similar operation for the second low-pass filter until a second capacitor code Qis determined, and calibrating for mismatch between the first low-pass filter and the second low-pass filter.
