Aneurysm implant requires multiple pressure sensors integrated into the stent graft for recording pressure profile inside an aneurysm sac. This paper details the design of an ASIC which receives power wirelessly using inductive coupling, fetches pressure data from a seperate chip and transmits data wirelessly. Besides, the ASIC extends the functionality of the external pressure measurement chip to support up to four pressure sensors by using an analog multiplexer. Error detection and forward error correction are implemented to improve data integrity for wireless data transmission. The design has been implemented and tested in 350 nm CMOS technology.
