Abstract: An amplifier circuit includes an input terminal used to receive an input signal, an output terminal used to output an output signal, an amplification unit, and a phase adjustment unit. The amplification unit includes an input terminal coupled to the input terminal of the amplifier circuit, an output terminal coupled to the output terminal of the amplifier circuit, a first terminal coupled to a first voltage terminal, and a second terminal coupled to a second voltage terminal. The phase adjustment unit is coupled to the amplification unit. When the amplifier circuit is operated in a first mode, the output signal has a first phase, and when the amplifier circuit is operated in a second mode, the output signal has a second phase. A difference between the first phase and the second phase is within a predetermined range.

Abstract: An imaging system for a living organism is described and has a receiving device used to receive the living organism and formed with at least two receiving grooves, at least one micro-channel connected to the receiving grooves, and a plurality of magnetic cilia disposed on a surface of the micro-channel; a magnetic field providing device neighboring a first side of the receiving device to control an action of the magnetic cilia; a driving device neighboring a second side of the receiving device to drive a movement of the living organism and control a moving direction thereof; a liquid providing device in communication with the receiving device to provide liquid; and an image capturing device neighboring a third side of the receiving device to capture an image of the living organism.
