Abstract: An arrayed switch circuit includes a substrate, signal conductive pads and signal expansion pins. The signal conductive pads are disposed on the substrate at intervals, and the signal conductive pads are arranged to form a signal conductive pad array. Each of the signal conductive pads has a row position and a column position in the signal conductive pad array. A row signal switch is provided between any two adjacent signal conductive pads corresponding to the same row position, and a column signal switch is provided between any two adjacent signal conductive pads corresponding to the same column position. The signal expansion pins are connected to the signal conductive pads located on at least one side of the signal conductive pad array through signal expansion switches respectively.

Abstract: A wideband transimpedance amplifier circuit is provided. The wideband transimpedance amplifier circuit includes a common-gate transistor, a bias current controlling circuit and an amplifier circuit. The bias current controlling circuit is coupled to a source of the common-gate transistor. The amplifier circuit is coupled to a drain of the common-gate transistor. The bias current controlling circuit adjusts the input impedance of the wideband transimpedance amplifier circuit according to the output signal of the amplifier circuit.
