Latest Patents

One of his latest inventions is a voltage reference circuit with a programmable thermal coefficient. This circuit comprises first and second bipolar transistors with their base terminals connected together and collector terminals linked to a current mirror circuit. The design includes an emitter terminal of the first transistor connected to ground through two resistors in series, while the second transistor's emitter terminal connects to a node between these resistors. Notably, the emitter of at least one of the transistors features discrete portions that can be electrically connected in a predetermined manner.

Another significant patent is a bandgap type thermal protection circuit for integrated circuits. This innovative circuit eliminates the need for a comparator and a voltage divider of the bandgap voltage. Instead, it utilizes a first transistor to mirror the current flowing through the bandgap circuit via a second transistor, which is functionally connected between the output node and ground. The control terminal of the second transistor is linked to a temperature-dependent voltage derived from the bandgap circuit, ensuring efficient thermal protection.
