Abstract
A reference voltage generator includes a first field effect transistor with n-type heavily doped gate structure and a second field effect transistor with p-type heavily doped gate structure. The first transistor is configured to have a gate and a substrate gate connected to ground, one terminal connected to a voltage supply, and another terminal connected to an output node. The second transistor is configured to have a gate and one terminal connected to the output node, and a substrate gate and another terminal connected to ground. The output node outputs a given reference voltage when voltage is supplied from the voltage supply. A voltage regulator that generates a constant voltage based on a given reference voltage incorporates the reference voltage generator.
