Title: The Innovations of Stefano Ramorini

Introduction

Stefano Ramorini is a notable inventor based in Milan, Italy. He has made significant contributions to the field of electronics, particularly in the design of voltage regulator circuits. His innovative approach has led to the development of a patented technology that enhances the efficiency of electronic devices.

Latest Patents

Stefano holds a patent for a Low-dropout voltage regulator circuit. This LDO regulator features a pass device arranged between an input node and an output node, controlled by an error amplifier at a control node. The design includes a first current generator that sources compensation current to the control node, while a cascode device is positioned between the control node and a compensation node. Additionally, a second current generator sinks compensation current from the compensation node. A compensation capacitor is placed between the output and compensation nodes, and the load current through the pass device is sensed to generate a feedback current at a first feedback node. An input branch of a current mirror receives this feedback current, and a filtering circuit is coupled between a control terminal of the input branch and a second feedback node. The output branches of the current mirror sink and source additional compensation current from the compensation node and the control node, respectively, in proportion to the feedback current. This innovative design improves the performance and reliability of voltage regulation in electronic applications.
