Most of the chip is digital logic, implemented with standard-cell circuitry, but there's lots of analog circuitry to handle the antenna signal. The four bond pads are where the antenna is attached. 9/15

Many chips use standard-cell circuitry. A program converts the logic description into rows of standardized blocks (NAND gates, flip-flops, etc.) and lays out the metal wiring between them. Much faster than creating an optimized layout by hand. 10/15
