Latest Patents

One of the listed inventions is titled “GPS Baseband Architecture.” It describes a receiver architecture designed to provide flexibility while reducing power consumption and chip area usage.

The architecture begins with a preamplifier connected to a low-noise amplifier and mixer. A phase-locked loop supplies the mixer with a frequency that converts the signal to a higher intermediate frequency. The signal then passes through a poly-phase filter and a programmable gain amplifier before reaching an analog-to-digital converter, which produces the GPS output signal. The converter’s saturation bit helps control the programmable gain amplifier through a digital automatic gain control circuit.

Career Highlights

Reis is associated with Synopsys, Inc., a company whose work includes semiconductor design and related technologies. His GPS baseband architecture patent reflects an engineering approach that combines analog and digital components to process satellite-navigation signals.
