Abstract: The generator has a PMOS transistor (43) mounted on a PMOS transistor (42) and connected to a load capacitor (51) to generate duplicate current for charging the capacitor. A control loop has a comparator, a filter and an integrator to control resistors (46, 47) and a MOS transistor (49) for generating a ramp having characteristics independent of dispersion characteristics of the resistors and temperature.

Abstract: An electronic circuit includes a substrate. A capacitor and at least one semiconductor component are supported by a surface of the substrate. A substantially planar screen, oriented parallel to the surface of the substrate and made of metallic material, is placed between the capacitor and the semiconductor component. Preferably, the semiconductor component is placed in proximity to the surface of the substrate and several superposed layers of insulating material cover the surface of the substrate and the semiconductor component. The capacitor is then placed within at least one layer of insulating material above the semiconductor component, and the screen is placed within an intermediate layer of insulating material between the layer incorporating the capacitor and the surface of the substrate.

Abstract: A voltage ramp generator includes a capacitance and a charging circuit that permits generation of a charging current for the capacitance. The charging circuit for the capacitance includes a current generator having a resistance Rg 2. The charging circuit for the capacitance includes components, such as resistance Re, that enables the capacitance charging current to be proportional to (Re/Rg 2 ) 2 . The voltage ramp generator is applicable to circuits for DC voltage converters operating in a current mode.

Abstract: An integrated circuit including an output pad, an output block coupled to the output pad via a capacitor, a first one-way conduction element for connecting the pad to a supply line when the voltage on the pad exceeds the voltage of the supply line by a first threshold voltage, a second one-way conduction element for connecting the pad to the circuit ground when the voltage on the pad is smaller than the ground voltage by a second threshold voltage, a resistor coupled on the one hand to the output pad and on the other hand to the supply line via a switch which is turned off when the circuit is idle and which is turned on when the circuit is in a normal operating mode.

Abstract: The protective circuit has a diode (D1) between the positive supply (A) and a node (N1) connected to an input/output pin (P1), and a second diode (D2) between the node and a negative or zero potential supply. A transistor (T1), in series between the node and positive supply, has a chain of diodes (1) between its collector and base, triggering conduction if an overvoltage occurs at the pin.
