Title: Marius Reffay: Innovator in CMOS Technology
Introduction
Marius Reffay is a notable inventor based in Grenoble, France. He has made significant contributions to the field of electronics, particularly in CMOS technology. With a total of 6 patents to his name, Reffay has developed innovative solutions that address various challenges in circuit design.
Latest Patents
One of his latest patents is a circuit for generating a floating reference voltage in CMOS technology. This circuit generates a reference voltage that is independent of temperature. It is built on a substrate according to CMOS technology and includes a first stage for generating a first current proportional to temperature and a second stage for generating a second current inversely proportional to temperature. These first and second currents are summed in a resistor connected to a voltage distinct from the ground of the first and second stages, formed by the voltage of the substrate on which the circuit is built. Another significant patent is a Class AB amplifier circuit, which includes a complementary output stage and a biasing circuit for biasing the output stage. The complementary output stage consists of a P-type MOS transistor and an N-type MOS transistor, while the biasing circuit includes a bipolar transistor. The emitter and collector of the bipolar transistor are connected to the gates of the P-type and N-type MOS transistors, respectively. The bipolar transistor is biased to control a bias voltage between the respective gates of the P-type and N-type MOS transistors.
