With a total of 3 patents to his name, Cheeranthodi's work has garnered attention for its innovative approaches and practical applications.

Latest Patents

One of his latest patents is focused on a system, method, and computer program product for setting phase control codes to (in-phase) I and (quadrature) Q rotators. This invention involves a first code pair that is different enough to produce a phase difference between the rotator outputs. This difference is sufficient to be detected with minimal error by a phase-to-voltage converter. Auxiliary trim DACs are adjusted according to calibration logic until a comparator output detects that the phase difference between the I and Q rotators is within tolerable limits. The resulting trim codes are stored for both codes in the pair. These trim codes, along with the main codes, are subsequently applied whenever the codes are used thereafter. The process is repeated with each successive code pair, ensuring that the phase separation between all code pairs is forced to the same value.
