摘要： 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.

摘要： A comparator including an amplifier unit, a latch unit, and a switch unit is provided. The amplifier unit receives and gains an input signal pair respectively and then outputs an output signal pair. The latch unit is coupled to the amplifier unit. During a tracking period, the latch unit is not powered, and during a latching period, the latch unit is powered to latch the output signal pair and then output a logical signal pair accordingly. The switch unit is coupled between the amplifier unit and the latch unit. During the tracking period, the switch unit transfers the output signal pair to the latch unit, and during the latch period, the switch unit separates the amplifier unit from the latch unit, and thereby reducing the influences to the comparator caused by the kick back noise and the offset error.
