Hello all,
I've been trying to make a TTL RC Oscillator as shown ( **broken link removed** ), and I've been able to do so with questionable success. It seems that for a given capacitance, the oscillator works for a given R +- a small fraction of R. I'm thinking that this might have something to do with the internal resistance of the inverters (I'm using LS04) or possibly the reactance of the capacitor that I'm not factoring in. One combination of C and R that worked for me was C=.01uF and R=5kΩ.
Thanks in advance
