A CMOS clock and data recovery circuit for intraocular microsystems

This paper presents the implementation of a clock and data recovery circuit (CDR) for intraocular microsystems. The CDR was designed to minimize chip area and power consumption and to recover the clock and data signals from the incoming data stream. Since the CDR has been designed without any external components it is well suited for being integrated in an intraocular microsystem. Simulation results show that this CDR works with power dissipation of less than 2.4 mW with a single 3.3 V power supply. The simulations are based on a 0.6 micron n-well CMOS single-polysilicon, three-metal technology.
