Title: Delta sigma modulation circuit
Inventor: HAYASE TORU
IPC: H03M7/32
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To extend a valid frequency band and/or dynamic range without being affected by quantization noise by setting a multiplier coefficient for a multiplier depending on an operating state in the delta sigma modulation circuit which converts an analog signal or a digital signal, represented in multi-bits into a 1-bit signal. SOLUTION: A frequency of a clock signal that is outputted from a clock generating circuit 12 to delay devices D1-D8 to specify a sampling timing is detected by a sampling frequency detection circuit 13 realized by a clock counter or the like. A multiplier coefficient is read selectively from a coefficient storage section 15 and set depending whether the sampling frequency is 32fs or 16fs. Thus, when the sampling frequency changes from 32f to 16fs, the valid frequency band is halved, but the desired valid frequency band is ensured regardless of reduction in the dynamic range.

Title: Vapor growth device
Inventor: TSUTAHARA KOUICHIROU
IPC: C30B25/14
Filed: 1990-09-10
Abstract: PURPOSE:To form the film in even thickness on a semiconductor wafer by a method wherein the title vapor growth device is provided with a protective block arranged at a distance from the second channel at a specific interval from a round body, a reactive gas jetting means to form a film on the semiconductor wafer held on a heating stage and the other jetting means of an inert gas from the first and second channels. CONSTITUTION:A semiconductor wafer 4 is heated and then reactive gas is jetted over the surface thereof to form a thin film thereon. When an inert gas is fed from an inert gas feeding hole 9, the inert gas is jetted out of a channel 12 and a circular channel 7 due to a resisting plate provided. Accordingly, enormous inert gas will not be jetted out locally per unit time thereby enabling the inert gas to be prevented from creeping in the semiconductor wafer 4. Furthermore, the width of the circular channel 7 is equalized with that of the channel 12 thereby equalizing the flow rate of the inert gas jetting from the peripheral parts of the semiconductor wafer 4 also reducing the local creeping-in of the inert gas to the least. Through these procedures, the thickness of the films formed on the semiconductor wafer can be made even.
