Title: Digital type comparator
Inventor: HASHIRANO MASARU
IPC: G01R25/00
Filed: 1987-11-25
Abstract: PURPOSE:To quicken pull-in of speed or a phase by making the period of a slope narrow only when a 2nd signal rushes from the minimum or the maximum value of a trapezoidal wave into the slope part to add the hysteresis characteristic. CONSTITUTION:The circuit constitution is adopted in such a way that the slope part is limited to a 2nd prescribed count period only when the 2nd signal S3 rushes from the minimum or the maximum of a trapezoidal wave to the slope part. Thus, the gradient of the slope is not changed at the rushing time to the slope part to make the slope period narrow and the minimum or maximum value is taken at the period made narrow. Since the slope part is used fully after the rush to the slope part, the locking is quickened in the event of the application of the speed control or phase control and the comparator having the similar dynamic range to that of a conventional comparator is obtained after pulling in.

Patent JP-H01140769-A (JP)
Title: Semiconductor device
Inventor: UEHARA KEIJIRO
IPC: H01L29/72
Filed: 1987-11-27
Abstract: PURPOSE:To shorten an isolation distance and to reduce an isolation capacitance by leading out a collector electrode from around a buried layer, and self-aligning the internal end of the collector electrode with a pattern for forming a base and an emitter. CONSTITUTION:Since a collector electrode 32 is formed around a buried layer 2, a distance in which a current flows is shortened, and thus a collector resistance is reduced. An isolation distance is formed by self-aligning a diffusion layer reaching the buried layer 2 around an isolated silicon island, whereby it is no longer required that the buried layer 2 whose size is larger be arranged in consideration of errors in matching masks, and thus said isolation distance can be shortened. The distance in which a current flows becomes so short that a sheet resistance slightly increases, but by making the buried layer 2 shallow, the isolation distance can still be made short. An isolation capacitance, which is a junction capacitance between the buried layer 2 and the substrate 1, decreases because the area of the buried layer 2 is substantially decreased, whereby the isolation capacitance and distance, etc., can be reduced.
