Designinstead of an antenna to capture electromagnetic energy field for being applied in smart-card applications.

The circuit is implemented to charge lithium cells (4mA 4.2V) to be targeted on the smart-cards with secondary batteries.

The figure shows schematic diagram of the charging architectural sytem. You will be taken into sections such the system architecture and the charging profile of rechargeable batteries,

description of the different blocks and their purpose (Mutual inductance coupling, Voltage limiter, Rectifier, Current regulation, Voltage regulation, Temperature control, Pass-element, OR-gate, Discharge stop), the overall chip and the measurement results.
