摘要： Provided is a frequency conversion mixer. The frequency conversion mixer includes a transconductance stage, a switching stage, a load stage, a current bleeding circuit, and a bias stage. The transconductance stage receives an RF signal, and outputs a current corresponding to a voltage of the RF signal. The switching stage switches the current which is outputted from the transconductance stage in response to a local oscillation signal, for frequency conversion the RF signal into an intermediate frequency (IF) signal. The load stage is connected between the switching stage and a supply voltage terminal. The current bleeding circuit is connected parallel with the switching stage, especially, embodying inverter structure with transconductance stage to get not only current bleeding effect but also current reuse effect, and one resonant inductor for reducing noise which is generated in parasitic capacitance at node between transconductance stage and switching stage. The bias stage is connected between the transconductance stage and a ground terminal, and has the switched biasing technique for allowing not only the stable bias current but also lowering the flicker noise.

摘要： Disclosed herein is an inverse transform method for an ultra-high resolution video codec. In the inverse transform method for an ultra-high resolution video codec using a Forward Discrete Cosine Transform (FDCT) algorithm, one of a plurality of pixel values is input as a first pixel value. One of remaining pixel values other than the first pixel value is input as a second pixel value. A first median value is calculated using a butterfly operation by applying coefficient values, respectively corresponding to the first and second pixel values, to the first and second pixel values. The first pixel value is replaced with the calculated first median value so as to re-perform the inverse transform method.
