    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: 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.

    Abstract: A phase modulation method with a polar transmitter. A target frequency is first designated by comparing the RF signal with a reference frequency and the phase sample. An oscillator control word is generated based on the target frequency. A digital oscillator can modulate from a first phase to a second phase to synthesize a preliminary RF signal based on the oscillator control word. When the target frequency exceeds the modulation capability of the digital oscillator, the oscillator control word is generated based on the target frequency minus 180 degrees, and the preliminary RF signal is shifted by 180 degrees to be the RF signal having the target frequency. When the target frequency does not exceed the modulation capability of the digital oscillator, the oscillator control word is generated solely based on the target frequency to output the preliminary RF signal to be the RF signal having the target frequency.
