Abstract
Official abstract text for this publication.
The invention provides a transmitter comprising two (or more) phase locked loops controlling respective oscillators, and implementing different phase modulation. Multiple phases are derived from the respective oscillators, and an edge rotator forms an output signal from a combination of the phases. The oscillators can operate at different frequencies, neither of which is an integer multiple of the other, whereas the output signals of the multiplexers of the first and second phase locked loops are closer in frequency and can be the same. This reduces the problem of pulling, with a circuit that can be implemented with low power and area and with the versatility of being digitally intensive.
First claim
Opening claim text (preview).
The invention claimed is: 1. A transmitter comprising: an all digital first phase locked loop controlling a first oscillator and receiving a first phase modulated signal; an all digital second phase locked loop controlling a second oscillator and receiving a second phase modulated signal; a power amplifier driven by the outputs of the first and second phase locked loops; a divider deriving multiple phases from the first and second phase locked loops; and an edge rotator as…
