DIODE_CANCELS_SUPPLY_CHANGES

Adding any small-signal germanium diode to Intersil 8038 sine-square-triangle function generator as shown will compensate for changes in supply voltage. When using diode, change from 10 to 15 V produces only 5-Hz change in output over frequency range of 100-10,000 Hz. Technique can be applied to other IC function generators, such as Signetics 565, as well ast to 555 timers.-R. Liebman, Single Diode Compensates IC 0scillator, EDN Magazine, April 20, 1974, p 87.
