Abstract: An intraocular pressure sensor is presented that achieve very low power consumption. The intraocular pressure sensor takes the form of an implantable assembly configured to be implanted in an eye of a subject. Specifically, the implantable assembly is comprised of a capsular tension ring attached to a flexible printed circuit board. The flexible printed circuit board includes a cutout that is sized to encircle the pupil of the eye and is C shaped. One or more electrical components are also mounted onto the flexible printed circuit board. One such component is a voltage reference generator that is implemented by a circuit which provides inherently low process variation and low power consumption.
