Title: Innovations of Inventor Sergio A. Sanielevici
Introduction
Sergio A. Sanielevici is a notable inventor based in Los Altos, California, recognized for his significant contributions to the field of communication systems. With a total of three patents to his name, his work reflects a blend of innovation and technical expertise, particularly in the modulation and demodulation of signals.
Latest Patents
One of Sanielevici's latest patents is the "Multi-level mixer architecture for direct conversion of FSK signals." This invention describes a multi-level quadrature (I/Q) mixer designed for communication systems like paging devices. The innovation features two I/Q downconversions followed by demodulation, with the first I/Q downconversion converting an I/Q signal pair to a first intermediate frequency (IF), while the second performs a similar process for a second IF. This approach allows for flexibility in downconverting single channels based on the number of subchannels.
Another significant patent is the "Direct demodulation method and apparatus," which introduces a demodulation circuit capable of detecting multiple zero-crossings in an FSK signal. By generating additional I and Q pairs that are phase-shifted from the original signals, this invention enhances the detection of zero crossings, facilitating the demodulation of high data rate modulated signals.
