The optical receiver for visible light communication replacing the traditional RF receiver effectively reduces the power consumption of IoT tags and makes the batteryless design feasible. In addition, the optical receiver provides a stable reference frequency referred to the input optical signal without external device such as crystal oscillator for low cost. The optical receiver is composed of a photodiode (PD), a front-end optical receiver and a clock and data recovery (CDR) circuit. The front-end optical receiver contains a transimpedance amplifier and a signal recovery circuit to regulate the voltage signal. The CDR circuit which is an all-digital reference-less phase-locked loop design is to generate a recovered clock to retime the data. Besides, the operation voltage of the circuits is 1V from the voltage regulator circuit since the IoT tags are powered by the small-sized solar cell whose output voltage is about 1.1~1.3V. The proposed circuits are simulated and fabricated via the TSMC 0.18um 1P6M standard CMOS process. The power consumption of the optical receiver is approximate as 7.1uW, and the data rate achieves 1Mbit/s. Furthermore, another chip with the front-end optical receiver and standard CMOS photodiodes are simulated and fabricated via the N-fab 0.35um 2P3M standard CMOS process. The bandwidth of the core circuit is 1MHz, and the power consumption is 8uW. Chao, Chang-Po 趙昌博 2015 學位論文 ; thesis 54 en_US |
