Abstract: An energy Internet system, an energy routing conversion device, and an energy control method, relating to a field of energy information. An alternating-current (AC) side energy routing conversion device of the energy Internet system includes a plurality of first route ports, and a direct-current (DC) side energy routing conversion device includes a plurality of second route ports, where each second route port is connected to a corresponding first route port by means of a corresponding DC busbar. A plurality of energy devices are connected to a DC busbar by means of corresponding first AC/DC converters or first DC converters. The AC side energy routing conversion device and the DC side energy routing conversion device collect energy information of the energy devices and adjust energy of the energy devices on a basis of energy balance constraint conditions.

Abstract: Disclosed is an operational amplifier based on a metal-oxide TFT. The operational amplifier includes an auxiliary amplifier and a bootstrap gain-increasing amplifier. The auxiliary amplifier adopts a two-stage positive feedback structure, including a fifth transistor, a seventh transistor, an eleventh transistor, a first amplifying unit, and a second amplifying unit. A gate of the fifth transistor serves as an input end of the operational amplifier. The bootstrap gain-increasing amplifier includes two second circuits in mutual symmetry. Each of the second circuits includes a first transistor, a second transistor, and a current source unit with a bootstrap structure.

Abstract: Disclosed is a charge-pump phase-locked loop based on a unipolar thin film transistor, a chip, and a method. The phase-locked loop may include: a phase-frequency detector, configured to detect a phase difference and a frequency difference between a clock Fref and a clock Fn and generate control signals UP and DOWN; a logic control module, configured to output logic state signals; a charge pump, configured to convert the logic state signals into a charging/discharging current signal; a low-pass filter, configured to output a direct-current analog control signal Vctrl; a voltage-controlled oscillator, configured to adjust an output clock frequency Fvco; and a divide-by-four circuit, configured to perform frequency division to obtain the clock Fn.
