Latest Patents
One of his latest patents is a polar signal generator. This invention relates to a method of deriving phase and amplitude components from in-phase (I) and quadrature-phase (Q) components of an input signal. The I and Q components are generated at a first sampling frequency and then up-sampled according to a predetermined interpolation factor. This process allows for the generation of up-sampled I and Q components at a higher sampling frequency, which can be converted into phase and amplitude components. The innovation enables I-Q generation and Cartesian-to-polar transformation to be performed at lower frequencies, thereby reducing power consumption.
Another significant patent by Van Zeijl is related to phase-to-frequency conversion for polar transmitters. This invention describes a polar transmission method and a polar transmitter that transmits phase and amplitude components derived from I and Q components of an input signal. The first conversion transforms the I and Q components into phase and amplitude components at a first sampling rate. A second conversion then changes the phase component into a frequency component, allowing for a lower update rate in a digitally controlled oscillator. This method enhances the approximation of the phase component, resulting in a cleaner spectrum around the synthesized channel.
