The invention discloses a power controlling apparatus for a biochip including M regions. Each region includes a plurality of cells respectively. The power controlling apparatus includes a pulse generating module, a combinational circuit, and M controlling modules. The pulse generating module generates a pulse. The combinational circuit receives the pulse and generates M controlling signals. Each controlling signal has a predetermined phase which is different from the phase of the other controlling signal. The M controlling modules are electrically connected to the combinational circuit. Each of the M controlling signals corresponds to and activates one of the M controlling modules to selectively power on one corresponding region of the M regions. The cells in the corresponding region which is powered have an action potential refractory time that is longer than the power-on interval of the corresponding region.

Power controlling apparatus applied to biochip and operating method thereof

An optical mouse chip with silicon retina structure comprises an image sensor array, an accumulator and a comparing/selecting unit. The image sensor array senses a direction parameter of an image along each axis. The accumulator sums the direction parameters of the image along different axes. The comparing/selecting unit selects a largest one from the sum of direction parameters of the image along different axes to determine a moving direction of the image.
