>But how would I go about doing something like that with OPAMPs exlusively?
Make square wave generator and integrate the output with opamp integrator. Then you just use another opamp to add offset/adjust gain and amplitude like pic related.
>Kind of want to stay away from digital solutions and keep this purely analog.
Why? While analog solutions are fun, it's hard to achieve higher frequencies, using digital signal generator IC is easier and allows you to reach >100 MHz easily. For audio frequencies opamps would be ok.
