Abstract
A method of reducing voltage variations in a power supply may include generating an intermediate voltage and setting a first-transistor gate voltage at a first-transistor gate of a first transistor of the power supply based on the intermediate voltage. The method may also include setting an output voltage at an output node of the power supply based on a second-transistor gate voltage at a second-transistor gate of a second transistor. Additionally, the method may include setting the second-transistor gate voltage based on the first-transistor gate voltage such that the output voltage is based on the intermediate voltage, a first-transistor threshold voltage of the first transistor, and a second-transistor threshold voltage of the second transistor and such that variations in the first-transistor threshold voltage and the second-transistor threshold voltage at least partially cancel each other out.
