Latest Patents

Miyo's latest patents include a feed-forward amplifying device and a method of controlling the same. This invention is particularly suitable for radio communication systems, such as digital automobile telephones. The feed-forward amplifying device features a distortion extracting loop circuit unit that includes a main amplifier, which amplifies a main signal. This unit creates a distortion extracting signal by controlling the phase of the main signal, effectively canceling the main signal component of the output from the main amplifier. Additionally, a distortion removing loop circuit unit is arranged at the rear stage of the main amplifier, producing only the main signal component from a signal in the main signal system. This innovative design improves power efficiency and produces a low-distortion amplified signal.

Another notable invention is a feedforward amplifier that incorporates a distortion detection loop and a distortion elimination loop. This design achieves increased accuracy, improved response, and stable operation. A variable attenuator is strategically placed in front of a detector in the loop output stage. The amount of attenuation is adjusted based on the amplifier's operational state, ensuring optimal performance during both transient and steady-state conditions.
