After the data signals are demodulated, they are passed along to a controller. e controller

uses the data to determine an appropriate setting for the current driver. e current driver then

drives the actuator, which is the component that actually applies the therapy to the patient. e

therapy varies based on the setting that is chosen by the controller. In this way, the therapy is able

to adapt almost instantaneously to the needs of the patient.

Li, Hu, and Zhang [11] were able to implement this design on a chip using a 0.5-μm 2P3M

standard CMOS process. e chip was tested in the human body temperature range, and the

results were successful. is circuit is a good representation of modern IMD design tech ...
