    Abstract: The interface circuit comprises one or two input branches and a single output branch. The output branch comprises two complementary transistors whose control electrodes are connected to the intermediate nodes of one of the input branches. The circuit serves as a voltage follower capable of feeding a further circuit which has a low input impedance. The interface circuit comprises one or two input branches and a single output branch. Each branch is connected between the upper and lower supply terminals. Each input branch includes a transistor whose control electrode is connected to the input of the interface circuit, and two other electrodes connected to the supply. A current source is placed between the supply terminals and an intermediate node connected to the last transistor node via one or more diodes. The output branch comprises two complementary transistors whose control electrodes are connected to the intermediate nodes of one of the input branches. One of the electrodes of each of the complementary transistors is connected to the output of the circuit. The last electrode of each of the transistors is connected to the supply terminal.

    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.
