Title: The Innovations of Didier Kaminsky
Introduction
Didier Kaminsky is a prominent inventor based in Paris, France. He has made significant contributions to the field of electronics, particularly in the development of advanced oscillators and frequency division circuits. With a total of 7 patents to his name, Kaminsky's work has had a notable impact on microwave technology.
Latest Patents
One of Kaminsky's latest inventions is the frequency-doubling voltage-controlled oscillator (VCO). This device operates in the microwave frequency range and features two channels that work in parallel. Each channel contains a transistor functioning as an oscillating system, with energy collected on the drain electrode. The innovative design reduces FM noise by mounting the transistors with their output currents in opposite phases. A varactor connected between the gates of the transistors achieves this phase opposition, while two capacitors decouple the varactor in direct current. To enhance frequency range, two additional varactors can be added to the source circuits of the transistors.
Another significant patent is the analog and aperiodic frequency divide-by-two circuit. This circuit operates from nearly DC up to the maximum frequency of the component devices. It utilizes first and second mixer stages to receive the signal and its antiphase complement. The output signals from the mixers are amplified and summed, with a portion of the sum signal fed back to the mixers. This innovative design allows the divider to be integrated on a single chip, capable of functioning at frequencies up to approximately 25 GHz.
