Latest Patents

One of his latest patents is the RF-to-baseband receiver architecture. This invention presents an improved receiver architecture and method for a wireless transceiver, such as headphones. The design allows for the use of a single synthesizer circuit for both RF-to-IF and IF-to-baseband conversion processes, leading to lower power consumption. The receiver incorporates an injection locked local receiver oscillator (Rx LO) for the first mixing stage, utilizing a high-level harmonic of a relatively low reference frequency signal produced by the synthesizer. Additionally, it features a tunable Q-enhanced IF filter and complex sub-sampling and mixing down-conversion circuitry for the second conversion stage.

Another significant patent is the method to reduce local oscillator or carrier leakage in frequency converting mixers. This invention discloses a method and system for minimizing local oscillator leakage from radio frequency mixers. Compensating circuits are employed to control the current in individual branches of a balanced input circuit of the mixer, thereby reducing unwanted leakage from the mixer output signal. The use of these compensating circuits results in high-quality signal transmissions.
