    Abstract: A circuit of a scanner to perform a color space conversion on an RGB signal. The circuit has several sampling-amplified-offset devices to sample, amplify and compensate potential of an R charge signal, a G charge signal and a B charge signal to obtain an R analog signal, a G analog signal and a B analog signal. The circuit further has a gain adder to multiply the corresponding weighted gain with the R analog signal, the G analog signal and the B analog signal. The multiplication results are then summed up to obtain an addition analog signal. A multiplexer is also included to select between the R analog signal, the G analog signal, the B analog signal and the addition analog signal for output.

    Abstract: An injection-locked frequency divider is provided and which includes an injection transistor, an oscillator, a current source and a transformer. The injection transistor is used to receive an injection signal. The oscillator is used to divide the injection signal to generate a divided frequency signal. The current source is coupled to the oscillator to provide a current to the oscillator. The transformer is coupled between the injection transistor and the oscillator to increase the equivalent transconductance of the injection transistor, and thus increasing the locking range of the injection-locked frequency divider.

    Abstract: In a method for inspecting the layout of a printed circuit board (PCB), a component to be checked is determined from an electronic layout diagram of the PCB, and a power transmission line which may be serving that component is selected. The layout diagram is checked to determine whether the component is connected to the power transmission line, and further checked to determine whether more than one ground pins of the component is connected to the power transmission line. Vias that are shared by two or more ground pins of the component are determined if more than one ground pin is connected to the power transmission line. Shared vias are marked on the layout diagram.
