Variable gain transconductance stage and that can be tuned adaptive filter

摘要

In an exemplary embodiment, I provide a communication device that has a (400) analog filter. Or, a desired value, in order to manage the position of the poles of the filter within a desired range, a digital signal processor (410), the gain of the analog filter (420, 440), the position of the pole of the filter (430, I set at the same time 480). In a further embodiment, the methodology of simultaneously setting the filter, and the position of the poles and the gain is also given. [Selection Figure Figure 4
