Latest Patents

Umeda's latest patents include an electronic tuner and a high-frequency receiving device. One of his innovations is a demodulator that features a reception quality evaluation circuit. This circuit evaluates the quality of a received signal by comparing it with a first reference value and outputs an evaluation signal. If the evaluation circuit determines that the quality of the received signal is acceptable, the power supply from the driving circuit to the DC offset control loop is stopped. This innovation offers a high-frequency receiver that significantly reduces power consumption. Another patent involves a high-frequency receiver with a gain switch controller. This device improves both interference resistance and reception sensitivity. The gain switch control unit includes a signal level determination unit that compares a gain control voltage of an amplifying circuit with a reference voltage. When receiving signals in areas with strong electric fields, the gain of the amplifying circuit is adjusted to be smaller, enhancing the receiver's performance.
