摘要： The invention relates to a detector of the mean level of a signal particularly intended to indicate whether an expected alternating signal is absent or present. This detector uses an analog comparator, a digital counter and a converter for establishing an analog signal to be compared with the expected rectified signal. The counter content oscillates round the mean value of the rectified signal. The counter serves as a digital integrator for the sign of the difference between the input signal and the content of the counter, in such a way that on average the input signal is just as often above as below the counter content. The digital - analog conversion can take place with the aid of switched capacitors.

摘要： A data transfer bus preloading circuit including a large sized transistor r ensuring rapid bus conductor preloading. This transistor is conductive at the beginning of the preloading step proper, but is blocked as the bus voltage reaches the desired preload value which corresponds to the sum of the respective threshold voltages of two other transistors of the circuit. The circuit includes five field effect transistors, two supply terminals, a preloading control input terminal and a preloading inhibiting input terminal. The large size transistor is connected between a first supply terminal and the output terminal of the circuit. A second transistor is connected between the gates of the first and third transistors. The gate of the second transistor is connected to the preloading control input terminal. The third transistor is connected between the source terminal and the fifth transistor. The gate and source of the third transistor are connected together. The fourth transistor is connected between the ground supply terminal and the gate of the first transistor. The gate of the fourth transistor is connected to the preloading inhibiting input terminal. The fifth transistor is connected between the third transistor and the ground supply terminal. The gate of the fifth transistor is connected to the output of the circuit. It is also possible to add a sixth transistor between the fifth transistor and the ground supply terminal with the drain and gate of this transistor being connected together.

摘要： This invention concerns an integrated-circuit amplifier incorporating CMOS (metal oxide semiconductor) technology, which amplifiers are capable of supplying a standardized 600 Ohm load, for example.This amplifier functions in class AB, and its output stage comprises an NPN bipolar transistor and an N-channel MOS transistor, connected in series in the same way as a conventional push-pull stage.The NPN transistor is controlled directly at its base by the signal for amplification. The control grid of the MOS transistor receives the output signal from a differential amplifier, one input of which is connected to the amplifier output S, the other input being connected to the emitter of another bipolar transistor, the base of which receives the signal for amplification.

摘要： The switch mode power supply includes a switching cell SC controllable cyclically and including only one inductive element L and several individually selectable outputs. During each conduction cycle, a total power level corresponding to the sum of the individual power levels respectively required by all the outputs OUTi during this cycle is injected into the inductive element L, the outputs requiring a non-zero individual power level are selected successively and in a predetermined order that is identical for all the cycles, and, at each selected output, the corresponding individual power level is produced.

摘要： The amount of charge passing through a measurement resistor connected to a rechargeable battery is measured by integrating in an analog manner an overall current. This overall current is equal to the sum of the resistor current and of a reference current that selectively takes one of two opposite values. The results of the integration are compared with a reference voltage, and one of two opposite values of the reference current is selected depending on each result of the comparison. The number of times where the positive opposite value of the reference current is selected furnishes an indication on the amount of charge during the integration time.
