    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 all-digital phase-locked loop is disclosed. The all-digital phase-locked loop includes a digitally controlled oscillator, a phase detector, a loop filter, and a bandwidth modification unit. The digitally controlled oscillator is controlled by an oscillator tuning word to generate a variable signal, wherein the oscillator tuning word includes a first tuning word and a second tuning word respectively to adjust the capacitance of a first capacitor set and the capacitance of a second capacitor set. The phase detector measures a phase error between the variable signal and a reference signal. The loop filter receives the phase error to generate an initial tuning word. The bandwidth modification unit receives the initial tuning word to adjust the initial tuning word to generate the tuning word according to the available usage range of the first capacitor set and the second capacitor set.
