Hi,
I am designing a ring oscillator whose output frequency is not sensitive to process and supply voltage variations. In order to do this i made the following current controlled ring oscillator. However, changing the bias current does not change the oscillation frequency of ring oscillator due to some reason. Can somebody tell how can i control the oscillation frequency from outside the chip so that i can adjust the frequency to compensate the supply and process variations.
regards
