An example circuit includes a first source follower input stage having a reference voltage input and a first output. A second source follower input stage has a feedback voltage input and a second output, in which second source follower input stage is configured to receive a feedback voltage at the feedback voltage input. The feedback voltage is representative of an output voltage at an output terminal of the circuit. A common gate differential gain stage has first and second differential inputs and first and second drive outputs. The first differential input is coupled to the first output, and the second differential input is coupled to the second output. The common gate differential gain stage is configured to control the output voltage at the output terminal by controlling at least one of the first or second drive outputs.
