A miniaturized liquid cooling device includes at least a heat absorber, at least a heat dissipater, a droplet generator driving a working fluid circulating between the at least a heat absorber and the at least a heat dissipater, and a plurality of tubes connecting the at least a heat absorber, the at least a heat dissipater and the droplet generator together to form a loop. The CDS device is coupled to a plurality of light-sensing pixels arranged along a first direction. A projection, for example a tang, extends from the platforms in a direction away from the longitudinal portion of the tip treatment component. The digital signal is received by a multiplexing circuit which outputs an analog signal corresponding the highest of the input signal amplitudes.
