摘要： A voltage regulator includes first and second bias circuits, a transistor, and a load prediction circuit. The transistor has a first current electrode coupled to a first power supply voltage terminal, a second current electrode for providing a regulated output voltage, and a control electrode. The first biasing circuit is for providing a first bias voltage to the control electrode of the transistor in response to a feedback signal generated from the regulated output voltage. The second biasing circuit is for providing a second bias voltage to the control electrode of the transistor in response to a control signal. The load current prediction circuit is coupled to the second biasing circuit. The load prediction circuit is for providing the control signal to the second biasing circuit in response to determining that a load current at the second current electrode is expected to increase.

摘要： The present document relates to multi-stage amplifiers, such as linear regulators or linear voltage regulators (e.g. low-dropout regulators) configured to provide a constant output voltage subject to load transients. A multi-stage amplifier (100, 200) is described. The multi-stage amplifier (100, 200) comprises a differential amplification stage (101) configured to provide a stage output voltage at an output node (255), based on a first input voltage (107) and a second input voltage (108). Furthermore, the multi-stage amplifier (100, 200) comprises a second amplification stage (102) comprising an amplifier current source (261) configured to provide an amplifier current; and an amplifier transistor (260) arranged in series with the amplifier current source; wherein a gate of the amplifier transistor (260) is coupled to the output node (255) of the differential amplification stage (101). In addition, the multi-stage amplifier (100, 200) comprises a detection circuit (300, 310) comprising a detection current source (301, 311) configured to provide a detection current; and a detection transistor (303, 313) arranged in series with the detection current source (301, 311); wherein a gate of the detection transistor (303, 313) is coupled to the output node (255) of the differential amplification stage (101). A mid-point between the detection current source (301, 311) and an input node of the detection transistor (303, 313) forms a sensing point (305, 315). The detection circuit (300, 310) is configured such that the sensing point (305, 315) changes from a default state to a detection state, subject to the stage output voltage at the output node (255) deviating from a default voltage by at least a predetermined threshold value.

摘要： Device comprising an electric power converter circuit for converting electric energy. The converter circuit comprises a switch arrangement with two or more controllable electric switches connected in a switching configuration and controlled so as to provide a current drive of electric energy from an associated electric source connected to a set of input terminals. This is obtained by the two or more electric switches being connected and controlled to short-circuit the input terminals during a part of a switching period. Further, a low pass filter with a capacitor and an inductor are provided to low pass the output from the switch arrangement and designed such that a high impedance at a frequency range below the switching frequency is obtained, seen from the output terminals. Switches implemented by normally-on-devices are preferred, e.g. in the form of a JFET. The converter circuit may be in different configurations such as half bridge buck, full bridge buck, half bridge boost, or full bridge boost. A current driven conversion is advantageous for high efficient energy conversion from current sources such as solar cells or where a voltage source is connected through long cables, e.g. powerline cables for long distance transmission of electric energy. In many applications the total size of filter components (capacitors and inductors) can be reduced compared to voltage driven topologies. One application is an audio amplifier arranged to drive a loudspeaker.
