This thesis presents that design of a WPT transmitter IC design for step-down solar power converter application, which is implemented by TSMC 0.18um 1P6M process technology. The designed circuits blocks include a DC to DC buck converter, a Low Drop-Out (LDO) regulator and a 2.4 GHz voltage-controlled oscillator. When the input voltage of DC to DC buck converter ranges from 3.8 to 5.2V, its output voltage will be at 3.3V. The transmitter’s operation frequency is 2.4 GHz. The output power of the integrated circuit is +3.19 dBm, with a total area is 0.88×1.262 mm2. The efficiency is 2.28%. If we combine the system with a power amplifier EPA2414, the efficiency will be increased to 14.98%.
