Abstract

In accordance with an embodiment, a power supply circuit includes: 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 including a third gate associated with a second transconductance and a fourth gate associated with a transconductance greater than the second transconductance. The second transistor device is configured to supply power to at least one load, 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.
