Latest Patents

Xudong Wang holds a patent for a "Transconductance-enhancing passive frequency mixer." This invention comprises a transconductance amplification stage, a frequency mixing stage, and an output transresistance amplifier. The transconductance amplification stage features a pre-amplification transconductance-enhancing structure, which greatly enhances transconductance. This allows for achieving the same transconductance value at a lower bias current. The frequency mixing stage modulates a radio-frequency current to generate an output mid-frequency current signal. This signal is then processed through the transresistance amplifier to produce a mid-frequency voltage signal. The design of the frequency mixer emphasizes low power consumption, high conversion gain, and good port isolation.
