DC-DC Boost Converter for Wireless Power Transfer Systems

This paper presents a DC-DC boost converter for wireless power transfer systems to treat tinnitus patients. The proposed regulated charge-pump based DC-DC boost converter circuit is implemented in a 180 nm high-voltage CMOS process. The use of a simple two-phase clocking scheme and charge sharing permits the use of higher operating clock frequencies compared to conventional solutions, thus obtaining high voltage gain and power efficiency. Simulations show good results with a supply voltage of 3.5 V and an 11-stage charge-pump that generates regulated voltages up to 20 V with a clock frequency of 65 MHz, small pump capacitor of 5 pF, and a 13 kΩ load resistor in series with 35 pF load capacitor.
