I'm trying to create a triangle wave that goes roughly from +100mV to close to max +V. I built a square wave using a 555 going from -V to +v, and can convert it to a triangle wave centered on ground using an op amp integrator.
But - I'm having trouble shifting the triangle wave to where I need it. But I'm having trouble shifting it to where I need it (i.e. completely on the positive side of ground). I tried capacitve coupling, but got a weird result. I tried using an op amp averager to +v, but also got weird results.
Does the integrator have a low output impedance? Do I need to buffer it?
Am I doing something else wrong?
What's the preferred way of doing this shift?
