text: Some circuits may use positive feedback and negative feedback around the same amplifier, for example triangle-wave oscillators and active filters.
text: Most circuits use negative feedback—or the return of part of the 180o out-of-phase output signal to the input signal—at either the inverting or the non-inverting input.
