Abstract
Parkinson's disease (PD) is chronic and progressive movement disorder, meaning that
symptoms continue and worsen over time. Nearly 0.4% people in Taiwan are living with
Parkinson's disease. The cause is unknown, and although there is presently no cure, there are
treatment options such as medication and surgery to manage its symptoms. Parkinson’s
involves the malfunction and death of vital nerve cells in the brain, called neurons.
Parkinson's primarily affects neurons in the area of the brain called the substantia nigra. Some
of these dying neurons produce dopamine, a chemical that sends messages to the part of the
brain that controls movement and coordination. The deep brain stimulation (DBS) method is
the best way to control the abnormal message of damaged brain cell by using current exciting
method and the stimulation module was installed in the human body. However, the battery of
this stimulation module need to change a new one every three year by surgical operations. In
this three year project, the enhancement-mode GaN HEMT on Si substrate technology will be
applied to design a wireless charger for DBS battery charge function. In the first year, the
E-mode GaN HEMT will be realized to drive 2W/mm output power and achieve a breakdown
voltage of 200V simultaneously. The high performance GaN device will be the active device
of the high efficiency wireless power source circuits. A 2000 ESD protection clamp will be
also designed in the second year for protecting the human body mode discharge damages. In
the last year, the flexible antenna, high power added efficiency class-F power amplifier will
be realized and integrated for the power source of wireless charger. The power receiver chip
in the human body will be demonstrated by a matching network and a high power, high speed
microwave power rectifier. The 2.5 V DC voltage will be obtained by receiving a RF power of
27 dBm and charge the energy to the battery of DBS system.
