Hello, I'd like to get some perspective in this area. 2 main enquiries.
1st being, in a Relaxation Oscillator Circuit, what are the parameters of the Op Amp that define the output voltage? [eg. slew rate, GBW, R-to-R] So say for example I have a ±5V supply [not V- or V+] for the OpAmp and I'd like to reduce the output voltage to 3V, what are the things I should look out for when selecting the suitable Op Amp.
My second part is related, that is if I were to follow up the circuit with a voltage follower/impedance converter to eliminate the effect of the extra 100 Ω at the output of the Oscillator Circ and maintain the output, which OpAmp would be suitable for the voltage follower - or better yet how does one begin to choose?
Thank you.
