Latest Patents

One of his latest patents is a blocking signal cancellation low noise amplifier system. This system includes a first low noise amplifier, a second low noise amplifier, a blocking signal extraction and bias generation circuit, a bias switching circuit, and a bias switching signal generating circuit. The first low noise amplifier is designed for dynamic input matching, receiving an input signal and outputting it after amplification. The blocking signal extraction and bias generation circuit extracts a blocking signal from the output of the first low noise amplifier and generates a DC voltage signal. The bias switching circuit allows the first low noise amplifier to switch between blocking mode and small signal mode, while the bias switching signal generating circuit compares the DC bias voltage signal with a preset reference voltage signal.

Another significant patent is the push-push frequency doubling scheme and circuit based on complementary transistors. This invention features a first differential amplifier circuit that receives a differential input signal with an initial frequency and amplifies the second harmonic of this signal to produce a first output. A second differential amplifier circuit performs a similar function, resulting in a second output. The first and second signals are differential signals with the same amplitude but a phase difference of 180°. The output load circuit extracts the second harmonic signals from both outputs, resulting in a pair of differential output signals with a frequency that is double the initial frequency.
