Abstract: A linear regulator is presented. It comprises a first amplifier stage, one of the inputs being coupled with the output of the linear regulator. It has an intermediate amplifier stage. The input of the intermediate amplifier stage is coupled to the output of the first amplifier stage. It has a driver stage having a pass device driven by the output of the driver stage. The output of the pass device provides the output of the linear regulator. The regulator has a voltage-to-current feedback circuit coupled with the driver stage and the output of the first amplifier stage for regulating the output resistance of the first amplifier stage depending on load conditions of the linear regulator. The voltage-to-current feedback circuit has a transistor and a current limitation circuit to limit the regulation of the output resistance of the first amplifier stage to low load conditions of the linear regulator.

Abstract: A measurement circuit for providing the maximum and/or minimum voltage of a time-variant electrical input signal is presented. The measurement circuit contains a voltage reference unit to provide voltage reference signals and a comparator unit comprising multiple comparators. Each comparator receiving the electrical input signal at a first comparator input and a different voltage reference signal from the voltage reference unit at its second comparator input.

The logic unit provides adaptation information to the voltage reference entity. The is adaptation information is dependent on the comparator output signals.

Abstract: A driver circuit for a switched-mode power converter is configured to perform hysteretic control of a switched-mode power converter. The switched-mode power converter comprises an inductor configured to store energy during a first state of the switch and to release energy towards a load of the switched-mode power converter during a second state of the switch. The driver circuit comprises a filter unit which is configured to determine a command signal based on a gate control signal applied to a gate of the switch. The command signal is indicative of a current through the inductor. The driver circuit comprises hysteretic control circuitry configured to generate the gate control signal based on the command signal; wherein the switch alternates between the first and second state when being subjected to the gate control signal.
