A photovoltaic (PV) system that operates at the maximum power point (MPP) is presented. In this system, in order to achieve maximum power point tracking (MPPT), a charge pump is used of which clock frequency is adaptable to a change in light intensity with the help of a luminance-controlled oscillator (LCO). The measurement results show that the harvested power is increased approximately by 50% over a wide range of light intensity due to MPPT. Based on the characteristics of the fabricated PV cells, the system was verified using 0.35-μm CMOS technology and implemented on a bread board..
