Latest Patents

One of Iwaida's latest patents is a variable gain amplifier. This innovative device includes a direct current (DC) blocking capacitor that receives an input signal at a first terminal. It features a variable amplifier unit with a variable transistor size that amplifies the output of a second terminal of the DC blocking capacitor. Additionally, it incorporates a load impedance unit coupled to the output of the variable amplifier unit, a bias resistor, and a variable bias voltage generator. The gain controller in this amplifier provides control to adjust the variable bias voltage based on the effective transistor size of the variable amplifier unit.

Another notable patent is related to a receiving device and electronic equipment using an image rejection mixer. In this invention, when a signal in the first radio frequency band is inputted, the first and second mixers convert the input signal to a signal in the first intermediate frequency band. A filter circuit is employed to attenuate an image interfering signal in the first intermediate frequency band. Similarly, when a signal in the second radio frequency band is inputted, the mixers convert it to a signal in the second intermediate frequency band, with a filter circuit that attenuates the image interfering signal in a narrower band.
