    摘要: The invention relates to a buffer circuit for a receiver device comprising a transconductance stage (105) and an output stage coupled in parallel to output stages of other channels of the device. The output of the transconductance stage (105) is connected to a base of a bipolar transistor (110) in the output stage. A switch (112) is connected between the base of the bipolar transistor (110) and the emitter of the bipolar transistor (110). A controller (120) is arranged to switch the buffer circuit from a switch-off mode to a switch-on mode and back. In switch-off mode the switch (112) is switched on, so as to connect the base and the emitter of the bipolar transistor (110).

    摘要: A power-conversion regulator comprising an inductive reactor, an output filter reactor, and a switch for admitting energy to the inductive reactor, additionally comprises computation circuitry responsive to the flux in the inductive reactor, to a reference signal, to an output voltage, and sometimes to an output load current, for computing the quantity of energy that must be supplied to a load and to the output filter reactor to regulate the output voltage or current to a desired relationship with the reference signal during each chopping waveform cycle driving the switch. As the inductive reactor is charged from an input energy source, the computation circuitry predicts whether the energy in the inductive reactor has become adequate for the regulation.
