Latest Patents

One of Johan's latest patents is the "Multi-level pulse width modulation power amplifier method and apparatus." This invention involves processing a baseband signal by amplifying a first pulse width modulation radio frequency signal with varying peak-to-peak amplitudes. The method allows for the constructive combination of amplified signals to create a pulse width modulation radio frequency signal that corresponds to different baseband signal power ranges.

Another significant patent is the "Amplifier modulation method and apparatus." This invention describes a process where a pulse-width modulation signal is generated and applied to a switched-mode amplifier. The output is then filtered to produce either differential mode oscillations or common mode oscillations, depending on the duty cycle of the pulse-width modulation signal. This innovation allows for amplitude modulations at the amplifier output by varying the duty cycle.
