Claim Text:
1. A circuit comprising: a differential amplifier comprising a differential pair comprising a first transistor and second transistor, each of the first and the second transistors comprising a front gate contact and a back gate contact; an inverting circuit having an input and an output, wherein the input of the inverting circuit is coupled to an output of the differential amplifier; a first node between the input of the inverting circuit and the output of the differential amplifier; a second node coupled to the output of the inverting circuit; a first digital feedback loop coupled between the first node and the back gate contact of the first transistor; and a second digital feedback loop coupled between the second node and the back gate contact of the second transistor, wherein the first digital feedback loop is configured to be opposite in phase to the second digital feedback loop.
