1. A power supply circuit comprising:
a first transistor device comprising a first gate associated with a first transconductance and a second gate associated with a transconductance greater than the first transconductance; and
a second transistor device comprising a third gate associated with a second transconductance and a fourth gate associated with a transconductance greater than the second transconductance, wherein the second transistor device is configured to supply power to at least one load, wherein the first and the third gates are controlled by a closed regulation loop, and the second and the fourth gates are controlled by a sampled reference voltage.
