Latest Patents

One of Cova's latest patents is the "Ultrasensitive photodetector with integrated pinhole for confocal microscopes." This innovative device features a semiconductor substrate of a first type of conductivity connected to a first electrode. The substrate comprises an active area made up of different semiconductor regions of a second type of conductivity, insulated from each other and connected to respective second electrodes. By regulating the bias voltages applied to these regions, the function of the optical diaphragm of the device can be controlled. This design allows the device to operate without needing any form of optical insulation between the different regions of the active area, utilizing the same single output electrode for the signal in all situations of diaphragm adjustment.

Another notable patent is the "Monolithic circuit of active quenching and active reset for avalanche photodiodes." This integrated circuit is capable of determining the quenching and reset of an avalanche photodiode operating in Geiger mode, enabling the detection of single photons. The circuit scheme reduces the size of the circuit to a single semiconductor chip, minimizes power dissipation, and lowers costs while maintaining good performance levels.
