Asking how to modify an existing circuit is an almost different question.
You see that the straightforward approach in the linked paper utilizes a fully differential OTA. Considering possible alternatives, I think that the right side can be implemented also single-ended, with a single capacitor. gm1 can be implemented respectively as regular differential in - single ended out OTA. gm2 must be differential out, or can be replaced by two single ended OTAs, one with flipped inputs. CMFB is probably required.
In other words, you need at least OTAs with differential input. Your basic single stage OTA can be theoretically used, in practice you want additional current mirror folding for useful output swing.
