Latest Patents

Zhao-Feng Zhang holds a patent for a "Tunable low noise amplifier and current-reused mixer for a low power RF application." This invention features a radio frequency front-end receiver that includes a single-stage low noise amplifier connected with a resistor array and a capacitor array. The Gilbert-type mixer is connected with a PMOS transconductance stage, an inductor, and a serially connected current source. The resistor array allows for the adjustment of the power gain of the low noise amplifier, while the capacitor array tunes the amplifier to achieve maximum power gain at the desired operating frequency. The PMOS transconductance stage is designed to reduce the power consumption of the mixer, and the inductor increases the impedance, improving the common-mode rejection of the mixer.
