Latest Patents
Takafumi Nasu holds a patent for a harmonic rejection mixer. This invention is designed to suppress high-frequency response while minimizing the increase in the number of gm elements. The harmonic rejection mixer regulates the waveform of an output signal by mixing outputs from multiple mixers connected in parallel with the latter stage of several gm elements. By sharing some gm elements between the I phase and Q phase, and utilizing a control signal with a duty ratio of less than 50%, the design allows for efficient operation. This innovative approach activates the Q-phase mixers during the inactive periods of the I-phase mixers.
