Latest Patents

One of his latest patents is the Double-balanced mixer. This invention includes a coupling transformer, a first diode cascade circuit, a second diode cascade circuit, and a first set of coils. The coupling transformer receives a first input signal and generates at least one set of signals with opposite voltage phases. The first diode cascade circuit is coupled to the coupling transformer and generates a first node voltage according to a first set of bias voltages. The second diode cascade circuit is also coupled to the coupling transformer and generates a second node voltage according to a second set of bias voltages. The first set of coils is coupled to the first and second diode cascade circuits, receives the first and second node voltages and a second input signal, and generates an output signal. Notably, the first node voltage is equal to the second node voltage.

Another significant patent is the Mixer circuit. This invention includes a mixer, a voltage divider circuit, and an amplifier. The mixer receives a first input signal, a second input signal, and at least one set of bias voltages, generating an output signal. The frequency of the output signal is related to the frequencies of the first and second input signals. The voltage divider circuit receives the bias voltages and generates a common mode signal at an output end. The amplifier is coupled to the mixer to receive the output signal and is also coupled to the output end of the voltage divider circuit. It is configured to suppress noise in the output signal and generate a final output signal.
