He holds three patents that showcase his innovative approach to improving technology in this area. His work has significantly impacted the design and functionality of radio frequency systems.

Latest Patents

One of his latest patents is titled "System and method of improving blocking immunity of radio frequency transceiver front end." This invention involves a power amplifier for a radio frequency transceiver that includes a driver, a disable circuit, and a bias circuit. The driver is designed to receive a drive voltage when enabled and has an output node that is susceptible to strong blocker signals when disabled. The bias circuit plays a crucial role in minimizing the impact of these blocker signals by driving the voltage levels of the source and output nodes to suitable bias voltage levels. Additionally, the disable circuit includes switch circuits that couple the driver to the bias circuit in the disable mode.

Another significant patent is the "Method and apparatus to remove the DC component of a feedback signal." This feedback circuit is strategically placed across the input and output terminals of an amplifier to prevent DC current from being injected back into the input terminal. The circuit comprises first and second current sources, a transistor, and a resistive load, ensuring that the DC voltages at the two terminals of the resistive load are substantially equal to inhibit DC current flow.
