Abstract :
We present in this paper a power recovery strategy dedicated to the biotelemetry application of cortical/nerve stimulation. The proposed strategy allows providing dual regulated output voltages 3.3V/1.8V to the electrodes driver and other implantable circuitry, respectively. Its low dropout voltage makes a high power efficiency attainable. One fabricated integrated prototype in a CMOS 0.18 μm technology has demonstrated its feasibility, providing a load current driving ability of 5 mA for each one of the two supply voltages.
