In this paper, we describe an ultra low-voltage high PSRR bandgap voltage reference circuit dedicated to implantable biomedical applications. The circuit takes advantage of the low gate-source voltage of weak inversion CMOS transistor. And by using negative feedback to generate a regulated supply, t...
