Abstract: In one embodiment, the electronic circuit includes a first amplifying circuit configured to generate a first compensation voltage based on a first reference voltage and an output voltage. The output voltage is from a functional circuit bloc. A second amplifying circuit is configured to generate a control voltage based on an input voltage, a second reference voltage and the first compensation voltage. The second reference voltage is different than the first reference voltage.

Abstract: A clock distribution circuit including a Phase Locked Loop (PLL), a first Phase Detecting and Converting (PDC) circuit, a second PDC circuit, and a clock generating and compensating (CGC) circuit may be provided. The PLL may generate reference clock signals. The first PDC circuit may generate input phase difference voltages based on phase differences between respective pairs of two reference clock signals among the reference clock signals. The second PDC circuit may generate output phase difference voltages based on phase differences between respective pairs of two power switching signals among power switching signals received from external switching regulators. The CGC circuit may generate input clock signals provided to the plurality of external switching regulators by shifting phases of the reference clock signals, and additionally control a phase of at least one of the input clock signals based on the input phase difference voltages and the output phase difference voltages.

Abstract: A charger circuit includes a first path regulator, a path switch, and a second path regulator. The first path regulator is configured to generate a first regulation current based on an input voltage and an input current. The path switch is configured to pass or block a first charging current in response to a control signal. The first charging current is generated based on the first regulation current. The second path regulator is configured to generate a second regulation current based on the input voltage and the input current. At least one of the first charging current and a second charging current is used to charge a battery. The second charging current is generated based on the second regulation current. The second charging current is transferred to the battery without passing through the path switch.
