Abstract
A high voltage regulator including a current mirror including a pair of transistors, one of the transistors being connected to a node that outputs an output voltage V, a diode stack that includes a plurality of serially connected transistors T, T, T, . . . T, wherein the transistor Tis connected to a node n, to which is connected another transistor Tthat receives an input bias voltage V, and wherein a feedback voltage fb from node nis fed to an input of the differential amplifier, the differential amplifier receiving an input reference voltage Vat one of its other inputs, and is also connected to positive voltage supply Vdd, the differential amplifier outputting to an NMOS transistor M, and wherein the high voltage regulator has a large diode stack gain and lower G*G*m, resulting in a generally constant feedback (loop) gain G, wherein the loop gain is given by:Loop Gain=
