摘要： A differential amplifier having a positive input terminal, a negative input terminal, an output terminal, a bias terminal and a ground terminal is provided. The differential amplifier comprises a differential pair circuit and a current mirror circuit. Wherein, the differential pair circuit is coupled to the positive input terminal, the negative input terminal, the output terminal, and the bias terminal of the differential amplifier. The current mirror circuit receives a constant current from a current source, and mirrors the constant current to the differential pair circuit. The current mirror circuit further connects to the ground terminal of the differential amplifier, and the terminal of the current mirror circuit receiving the constant current is coupled to a first source/drain terminal of a first PMOS transistor. A second source/drain and a gate of the first PMOS transistor are connected to the bias terminal and the output terminal of the differential amplifier, respectively.

摘要： The present invention relates to battery chargers. A first controller can be configured to set, when a first power supply is coupled to a first port, a current produced by a variable current source at a safe rate to charge a battery. An ammeter can be configured to measure, when the battery is coupled to a second port, the current flowing into the battery. The first controller can be configured to increase, after a passing of a quantifiable amount of time, the current produced by the variable current source by a quantifiable amount of current. The first controller can be configured to continue iteratively to increase, after the passing of the quantifiable amount of time, the current produced by the variable current source by the quantifiable amount of current until the safe rate is near or at a highest safe rate to charge the battery.
