Power management is a fundamental block in integrated circuits, especially for battery-operated systems such as the Magnetic Resonance Imaging transceiver which requires these Low-Dropout Regulators (LDO). LDOs are DC linear voltage regulators built to regulate an output voltage powered from a higher-voltage input. To supply the different building blocks of the MRI transceiver, two LDOs have to be designed. On one hand, an LDO which will be coupled with a DC-DC converter to supply most of the building blocks. On the other hand, an LDO dedicated to the reference oscillator responsible for delivering the main clock of the system. The latter will be more challenging with adjustable input and output voltages.

Short Description

Implantable devices have seen a large growth in the past years. For humans pacemakers are most common, but more recently other implants like insulin pumps or even cochlear implants have emerged. They all need electrical power that usually is provided from a battery. When only small currents are drawn from the latter then the battery can last long until it needs to be replaced. Wireless charging offers a way to circumvent the exchange for rechargeable batteries.

At the IIS we have developed miniaturized circuits for implantable devices, in particular a power management IC. In this project an extension to it for wireless charging will be investigated. It includes the whole transfer chain as shown in the picture, with the transmit driver, the coils and the charging part on the side of the implant.
