Abstract
Method and apparatus for providing a lateral double-diffused MOSFET (LDMOS) transistor having a dual gate. The dual gate includes a first gate and a second gate. The first gate includes a first oxide layer formed over a substrate, and the second gate includes a second oxide layer formed over the substrate. The first gate is located a pre-determined distance from the second gate. A digitally implemented voltage regulator is also provided that includes a switching circuit having a dual gate LDMOS transistor.
