Title: Innovations of Jean A Chabas
Introduction
Jean A Chabas is a notable inventor based in Cesson Sevigne, France. He has made significant contributions to the field of electronics, particularly in radio devices and electronic apparatuses. With a total of 3 patents, his work showcases innovative solutions that enhance the functionality and efficiency of electronic systems.
Latest Patents
One of his latest patents is a radio device that includes a frequency synthesizer and a phase discriminator. This device features a phase discriminator with a phase-locked loop. When there is no phase locking, the output voltage of the phase discriminator remains constant, providing considerable gain for the loop. Conversely, when phase locking occurs, the phase discriminator produces an error proportional to the phase difference. The output of the phase discriminator maintains a constant amplitude even when the input signal and reference signal have different frequencies.
Another significant patent is an electronic apparatus comprising a power amplifier. This apparatus includes an output stage that has a non-linear amplification characteristic, along with a correction assembly designed to compensate for the non-linearities of this characteristic. The correction assembly consists of a low-power preamplifier of the same type as the power stage, which presents the same non-linearity. The combining device effectively counteracts the non-linearities of the characteristics by combining the signals applied to the input terminal with the output signals of the preamplifier.
Career Highlights
Throughout his career, Jean A Chabas has worked with prominent companies, including U.S. Philips Corporation. His experience in these organizations has contributed to his expertise in developing innovative electronic solutions.
