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.

Abstract: Provided are a semiconductor device and a method of operating the same. A semiconductor device may include a comparator which compares a first voltage with a rectified voltage and provides a second voltage in accordance with the comparison. A timer circuit may operate a timer according to the second voltage and output a third voltage in correspondence with an operation time of the timer. A driver may drive a transistor with a fourth voltage generated by the driver according to the third voltage. A calibration circuit may generate a timer calibration signal based on the second voltage and the fourth voltage. The timer calibration signal may be provided to the timer circuit and used to calibrate the operation time of the timer. More efficient rectification, with reduced occurrence of reverse current, may thereby be realized.

Abstract: A signal generation circuit includes: a clock signal generator configured to generate a clock signal and to change a frequency of the clock signal in response to a select signal; a transmission control circuit configured to control transmission of the clock signal based on the select signal; and a counter configured to perform an operation among a count operation and a count stop operation based on an output signal of the transmission control circuit and to output the select signal based on a result of performing the operation. When the counter performs the count operation in response to the clock signal output from the transmission control circuit, the counter outputs a most significant bit (MSB) among its count bits as the select signal.
