Abstract: An output buffer includes at least a first and a second stage, wherein each stage is formed by respective first transistors and second transistors coupled in series with each other between a first and a second voltage reference. The coupled first and second transistors have a common conduction terminal connected to an output terminal of the output buffer. An input terminal of the buffer is connected to control terminals of the transistors of the first stage through a first open loop driving circuit. A second feedback driving circuit is connected between the input terminal and the control terminals of the transistors of the second stage. The second feedback driving circuit includes a current detector operating to detect a maximum in the value of the current drawn by and supplied to the output buffer. A comparison block, having a threshold value, detects current in excess of the threshold value and processes information coming from the current detector to regulate an output impedance value of the output buffer.

Abstract: An inductive structure having at least one winding or at least one coil and developed around a ferromagnetic core. Advantageously, the ferromagnetic core is formed by means of a multilayer ferromagnetic structure and the inductive structure is integrated in an electronic device. An inductor, a transformer, a sensor and a relay can be formed by means of the inductive structure proposed, as well as a method for integrating it in a package of an electronic device.

Abstract: A low supply voltage memory device includes a first supply pin and a second supply pin for the connection to a first supply voltage source (VDD) and to a second supply voltage source (VDDQ). The device may include a memory and at least one booster overlapped by way of a “system in package” system and in particular with “stacked-die” technology. This booster may be connected to the memory by way of a plurality of discrete components.
