  • Abstract
    Switched-current (SI) circuits are suitable to operate on the same chip with digital circuits in low-voltage supply. This property is very important for applications in portable devices like digital cameras. Switched-capacitor implementation of the two-dimensional (2D) discrete cosine transform (DCT) was reported in the literature. In this paper, the design method of a 2D DCT for SI implementation is presented. An experimental chip was fabricated in AMS CMOS 0.8 /spl mu/m technology. The results of testing are reported.
