SQUARE WAVE GENERATING CIRCUIT ARRANGEMENT

摘要

SQUARE WAVE GENERATING CIRCUIT ARRANGEMENT An output wave regenerating stage following an operational amplifier stage and arranged within a dual path feedback loop delivers a symmetrical square wave of frequency and symmetry unaffected by ambient temperature and energizing supply potential variations over a broad range. Output voltages swing within the supply potential by a drop equal to the value of the Vce saturation voltage, and low grade operational amplifiers commercially available with non-symmetrical output saturation levels can be used without degrading performance.
