摘要： The invention provides a differential current output unit that has a least number of capacitors and a minimized chip area on one hand, and on the other hand that is capable of providing a smoothly varying output current across a zero-crossing point in accord with an inputted difference input voltage. To do this, the differential current output unit is entirely formed of differential circuits and current mirror circuits having predetermined current mirror ratios. Thus, the unit has a stable output current characteristic. The unit has an inflow output transistor circuit and an outflow output transistor circuit that are operably separated by a delivery circuit. Thus, no penetration current will flow through the inflow- and outflow-output transistor circuits.

摘要： A pattern inspection apparatus for accurately inspecting a pattern such that design image data is processed in correspondence to resizing of a pattern to be inspected. Image data corresponding to an image area of a predetermined size is extracted from input information represented by binary logic levels and representing a pattern to be resized. Template circuits add additional data of a predetermined logic level to a predetermined pixel position when a distribution of the image logic levels included in the extracted image data is a predetermined distribution. Thus, the additional data is added to the pattern image data to resize the pattern.
