Abstract

A system to evaluate a voltage in a charge pump may include a transistor, and a transistor drain carried by the transistor with the transistor drain receiving a reference current. The system may also include a transistor gate carried by the transistor and connected to the transistor drain. The system may further include an additional transistor and an additional transistor gate carried by the additional transistor and connected to the transistor gate. The system may additionally include an additional transistor drain to receive the reference current mirrored from the additional transistor.
