Hi i have designed a ciruit usin the lm331 but iam facing a problem in which the output freuqency keeps on fluctuation let say for example at 1volts it varies from 1khz to 100khz where as it should remain fixed at 1khz can any one suggest me chnages in my circuit
I would think you have a bad joint somewhere or instability, have you put decoupling capacitors across the local Vcc line to earth? and kept your input leads away from the output?
