“…Normally for a typical DBS system, the size of an IPG is less than 47 mm × 52 mm × 11 mm and approximately half of the IPG space might be filled by the battery [9]. Therefore, we start the antenna design by limiting the size of the small modified Minkowski fractal antenna to a rectangular path antenna with a dimension of 20 mm × 20 mm × 1.6 mm.…”

A small planar modified Minkowski fractal antenna is designed and simulated in dual frequency bands (2.4 and 5.8 GHz) for wireless energy harvesting by deep brain stimulation (DBS) devices. The designed antenna, physically being confined inside a miniaturized structure, can efficiently convert the wireless signals in dual ISM frequency bands to the energy source to recharge the DBS battery or power the pulse generator directly. The performance metrics such as the return loss, the specific absorption rate (SAR), and the radiation pattern within skin and muscle-fat-skin tissues are evaluated for the designed antenna. The gain of the proposed antenna is 3.2 dBi at 2.4 GHz and 4.7 dBi at 5.8 GHz; also the averaged SAR of the antenna in human body tissue is found to be well below the legally allowed limit at both frequency bands. The link budget shows the received power at the distance of 25 cm at 2.4 GHz and 5.8 GHz are around 0.4 mW and 0.04 mW, which can empower the DBS implant. The large operational bandwidth, the physical compactness, and the efficiency in wireless signal reception make this antenna suitable in being used in implanted biomedical devices such as DBS pulse generators.

This thesis proposes an Integer-N frequency synthesizer in TSMC 0.18µm technology. The design is aimed for MICS (Medical Implantable Communication Services) devices operating at 402-406 MHz. A low phase noise, wide frequency range Quadrature Voltage Controlled Oscillator (QVCO) has been designed and simulated. The simulated phase noise @ 160 KHz offset is -100.3 dBc/Hz with the power consumption of 0.9 mW. This design addresses the small size, low phase noise and low power requirements for the Implantable devices. A wide frequency range Source Coupled Logic (SCL)32/33 prescaler divider has been designed. The program counter and Swallow counter have been implemented in Verilog-A which allow a division ratio of 2690 from the output of the QVCO. A phase frequency detector based on a modified TSPC D-Flip Flop is designed, which leads to a faster response time. The phase frequency detector, the charge pump, and the loop filter would consume 0.5 mW power. The total power consumption of the synthesizer is at 4.6 mW with 2% steady state settlement time of 160 μs.
