Abstract: A cascaded amplifier is comprised of a number of amplifying stages connected in cascade such as the dual emitter-coupled amplifier shown. A first pair of transistors (14,20) provides limiting amplification and a second pair of transistors (16,18) with degeneration (22,24) provide linear amplification. Each pair of transistors is driven by a current source (28,26) which supplies a current (IT, IT2) proportional to absolute temperature (PTAT). The small signal amplification is then substantially independent of temperature and the value of the limited output is proportional to absolute temperature. This latter effect is countered by including a translinear variable current gain amplifier (54,56,58,60) in the last dual-gain stage of the cascaded amplifier to modify the output voltage in a manner inversely proportional to absolute temperature. A transfer function may thus be provided which is substantially independent of temperature.

Abstract: An automatic language determining apparatus automatically determines the particular Asian language of the text image of a document when the gross script-type is known to be, or is determined to be, an Asian script-type. A connected component generating means (28) generates connected components from the pixels comprising the text image. A character cell generating means generates a character cell surrounding at least one connected component. An optical density determining means determines the optical density, in absolute numbers or percentage of pixels, of the pixels within each character cell. A script feature determining means first generates a histogram, then converts, by linear discriminate analysis, the histogram to a point in a new coordinate space. A language determining means (36) compares the determined point of the text portion in the new coordinate space to predetermined regimes in the new coordinate space corresponding to at least one Asian language to determine the particular Asian language of the text image.
