A new method of analog-digital conversion of signal is reported, by using the output current of a solar-cell (used as an illumination sensor) as a Vdd source for a voltage-controlled oscillator, thereby directly converting the illumination signal into frequency. *Reference [#j29cdcf5] +&color(black){%%%Shunsuke Yamada%%% and Hiroshi Toshiyoshi, "An Illuminance Sensor Integrated with Analog Digital Converter using Pulse Density Modulation," [[IEEE Sensors 2017]], Oct. 30-Nov. 1, 2017, Grasgow, Scotland, UK.};
