Abstract
PURPOSE:To obtain a low frequency stable output, by providing an osicllating part for a comparatively high frequency, a frequency dividing circuit which divides the output of this oscillating part into a prescribed value, and an integrating circuit which integrates the output of this frequecy dividing part. CONSTITUTION:A high-stability oscillating circuit 1 consisting of inverters 7, 8, and 9 including a quartz oscillator 10 is constituted. The oscillation output is divided into a desired frequency by a frequency dividing circuit 2, and the level is adjusted by a level setting part 3 consisting of an operational amplifier 11 and resistances 12 and 13. The rectangular wave is converted to an artificial sine wave by integrating parts 4 and 5 consisting of operational amplifiers 4 and 5, resistances 16 and 17, and capacitors 18 and 19, thus obtaining a high-stability output of <=1Hz low frequency from an output terminal 6.
