Latest Patents

One of her latest patents is the "Image Rejection Mixer." This invention features an image rejection mixer designed to reduce power dissipation. It includes a signal distributor that supplies local signals with a phase difference, distributing these signals to a first and second signal mixer. These mixers combine the distributed local signals with RF signals, outputting respective IF current signals. A phase shifter then adjusts the phase of these mixed IF current signals, providing a relative phase difference of 90 degrees. Finally, a signal adder combines the phase-shifted intermediate frequency current signals.

Another significant patent is the "Semiconductor Integrated Device." This device comprises a functional circuit with multiple signal terminals and an ESD protective circuit. The protective circuit includes a pair of protective diodes connected in reverse between each signal terminal and a power source or ground line. Additionally, it features a bipolar transistor with a current path between the power source and ground, along with a capacitor connected between the collector and base of the transistor. This design effectively protects against ESD surges by forming a current path for discharge.
