Cascode amplifier with increased linearity

Abstract: An amplifier circuit for current amplification An input stage is adapted to receive an input signal At least one current multiplication stage is connected to the input stage The current multiplication stage is adapted to receive a current signal from the input stage and to produce a multiplied output current signal at an output of the amplifier circuit The current multiplication stage includes at least two current multiplication circuits connected to each other Each current multiplication circuit is adapted to produce an output current signal essentially equal to the current signal from the input stage, such that the output current signal at an output of the amplifier circuit includes a sum of the current signals received at each current multiplication circuit A method of improving linearity in an amplification circuit

Image-based rendering (IBR)

Abstract: The present invention relates to computer production of images. Three-dimensional graphics data (D3D) is automatically rendered by means of a GPU (330), which is adapted to receive two-dimensional image data. This data contains a number of image points, which each is associated with color information (r, g, b), transparency information (a), and depth buffer data (Z) that for each of the image points specifies a distance between a projection plane and a point of a reproduced object in the scene. A buffer unit (320) storing the image data is directly accessible by the GPU (330). The GPU (330), in turn, includes a texture module (331), a vertex module (332) and a fragment module (333). The texture module (331) receives the color information (r, g, b) and based thereon generates texture data (T) for at least one synthetic object in the synthetic three-dimensional model (V). The vertex module (332) receives the depth buffer data (Z) and based thereon generates geometry data (G) for each of the at least one synthetic object. The fragment module (333) receives the transparency information (a) and the depth buffer data (Z), and based thereon, generates surface property data (S) for each of the at least one synthetic object.
