摘要： Attenuation cell comprising first and second differential pairs of bipolar transistors. A gain control device applies a voltage VA−VB between the bases of both differential pairs and comprises a set of three diodes in which a current IA, a current IB and the sum IA+IB of both preceding currents flow, respectively. The two diodes seeing current IB and IA+IB generate a voltage, respectively VB and VC, and the difference between these two voltages is used to generate a value Iz used in a control loop. A desired value Vct is transformed into information Ix, then into information Iy proportional to absolute temperature T, and an error amplifier uses information Iy−Iz and generates currents IA and IB by minimizing this difference.

摘要： 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.
