    摘要： Provided is a colpitts quadrature voltage controlled oscillator capable of obtaining quadrature orthogonal signals using a quadrature combination between a base and a collector of each transistor, without using an additional circuit such as a coupled transistor, a coupled transformer, a multiphase RC filter, etc. Accordingly, since nonlinearity, increased phase noise, a decrease in the Q-factor of an LC resonator, and increased power consumption can be avoided, a colpitts quadrature voltage controlled oscillator that has low phase noise, low electric power consumption, and a compact size can be implemented.

The photo diode includes: a p-type well; an internal n-type region formed under a surface of the p-type well; and a surface p-type region including a highly doped p-type SiGeC epitaxial layer or a polysilicon layer deposited on a top surface of the p-type well over the internal n-type region. The image sensor includes: a photo diode including an internal n-type region and a surface p-type region; a transfer transistor for transmitting photo-charges generated in the photo diode to a floating diffusion node; and a driving transistor for amplifying a variation in an electric potential of the floating diffusion node due to the photo-charges. The image sensor further includes a floating metal layer for functioning as the floating diffusion node and applying an electric potential from a drain of the transfer transistor to a gate of the driving transistor.
