With a total of 2 patents to his name, Ribas continues to push the boundaries of innovation in his industry.
Latest Patents
One of Ribas's latest patents is a calibration device for a video input stage. This invention features an input stage for a video receiver that includes a variable gain amplifier, an analog-to-digital converter for sampling a video signal, and a digital processing unit for processing digital samples of the video signal. An analog regulating circuit sets an input potential at the input of the variable gain amplifier. The use of a differential architecture for the variable gain amplifier and the digital analog converter allows for the generation of the video signal on two channels in antiphase, centered on the common mode voltage. This architecture reduces the amplitude of analog signals, which is particularly beneficial when operating with low voltage supplies. Additionally, it enhances the linearity of video signal processing.
Another notable patent is a mirroring circuit designed for operation at high frequencies. This circuit includes a first branch with a first transistor in series with a first resistor, and a second branch with a second transistor in series with a second resistor. A servo circuit controls the current flowing in both branches, ensuring efficient operation. The design incorporates multiple transistors configured as diodes and shift levers, optimizing the circuit's performance.
