Latest Patents

Ding’s listed patents concern circuit designs intended to manage signal amplification, impedance, and parasitic capacitance in RF systems.

Low Noise Amplification Circuit. This invention combines an RF amplification circuit, an output impedance matching circuit, and an attenuation network. It also includes a passive attenuation path and an impedance regulation network. The regulation network is configured to resonate with parasitic capacitance in different operating modes, including capacitance associated with the attenuation network and the passive attenuation path.

Input Impedance Matching Network and Radio Frequency Front-End Module. This invention uses a first inductor connected between two pads, with the second pad serving as the output toward a low-noise amplifier. A compensation regulation circuit adjusts parasitic capacitance from one or both pads to ground. The design is configured so that the first pad’s parasitic capacitance to ground is greater than the second pad’s.
