Abstract
A battery simulation circuit simulates a rechargeable battery. The battery simulation circuit includes an integrated amplifier, a voltage adjustment unit, a current limitation unit, and a feedback unit. The voltage adjustment unit provides a reference voltage for the integrated amplifier; the current limitation unit provides a reference current for the integrated amplifier and the feedback unit provides a negative feedback signal for the integrated amplifier to control the integrated amplifier working in a linear state. The integrated amplifier outputs an output signal according to the reference voltage and the reference current; the battery simulation circuit supplies power for an electronic device. When the output terminal is connected to a DC power source and a voltage of the DC power source is greater than the output voltage of the output terminal, the battery simulation circuit simulates a battery being recharged by the DC power source via the output terminal.
