Latest Patents
One of Zhaofeng Zhang's latest inventions is a low noise amplifier with switch gain control. This invention presents a low noise amplifier that includes an impedance matching circuit, a switch circuit, a signal amplifying branch circuit, a switch control circuit, a signal attenuating circuit, and a current bias circuit. The switch circuit controls signal amplification or attenuation based on the input signal level. This invention provides low noise, great dynamic range, increased system integration, and low power consumption. It is particularly useful for integrated circuit wireless communication systems and RF preamplifiers for receivers.
Another notable patent is the binary frequency-shift keying demodulator and frequency-to-voltage converter. This BFSK demodulator comprises a three-channel frequency-to-voltage converter. It includes an information signal inputting the first-channel frequency-to-voltage converter and a converted information signal inputting the second-channel frequency-to-voltage converter. The outputs of the first and second channel frequency-to-voltage converters are connected with a capacitor. An output voltage signal is produced by these converters and the capacitor, which is then input into a comparator after high-frequency noise filtering through a low-pass filter. A carrier signal is input into the third-channel frequency-to-voltage converter, and a reference voltage signal is produced after filtering, resulting in a demodulated signal.
