Latest Patents
Vanni Poletta holds a patent for a "Biasing network for multifunction bipolar integrated system." This invention provides a network for supplying identical biasing voltages and programmable direct currents to multiple similar transceivers. The design integrates a generator of fixed reference voltage, determined by the semiconductor's band gap, which is applied in parallel to the bases of several NPN transistors. This configuration ensures that the transistors emit the same biasing voltage. Additionally, the reference voltage drives an NPN pilot transistor, which draws a small programmed current through an external resistor. The invention features two cascaded amplification stages formed by NPN transistors operating in the ECL mode, with the second stage designed as a multiple-output current mirror. This setup allows the programmed current to be stepped up, providing the necessary direct currents for the associated transceivers.
