A passive integrated visible light communication（VLC） receive module is presented based on silicon photocell for optoelectronic identification（OEID）. Silicon photocell can detect and convert the optical signal into electrical signal without additional energy supply. With this characteristic, we use it as VLC receiving device for passive detection and transmission of optical signals in space. The circuit is designed with TSMC 0.18 μm standard CMOS processes. The photocell works in the illumination of 500 lx, it can provide power management with 2 V input voltage and 1.8 V output. The 3 d B bandwidth of the receive part is 67.2 kHz. Output of the overall chip is 0-1.8 V standard digital signal, with area of 615×460 μm^2.Static power consumption of the circuit is about 1.5 mW.
