碩士 === 國立臺灣科技大學 === 電子工程系 === 95 === In this thesis, a study of optical-current-controlled oscillator is presented. The CMOS process provided by CIC (Chip Implement Center) is used. Here, we study three ICs: the transimpedance amplifier and the ring-type voltage-controlled oscillator and LC-type voltage-controlled oscillator. The first part deals with three types of transimpedance amplifiers. That are linear type, and RGC type, RGC linear type. The amplifiers we designed have 81.9dBΩ,49dBΩ and 74.7dBΩ gains, respectively. Their bandwidths are 257MHz,2.73GHz and 522MHz, respectively. In the second part, the designs of ring and LC voltage-controlled oscillators are presented. The frequency tuning range of ring VCO is 1.09GHz∼1.55GHz in our design. The frequency tuning range of LC VCO is 3.15GHz∼3.82GHz in our design. The range of controlled voltage is 0V∼3.3V. The measured result of frequency tuning range of our ring VCO is 676MHz∼906.3MHz. Finally, the combination of the above mentioned two building blocks can be applied to optical-intensity controlled electrical oscillators. It has potential applications to the radio over fiber in the monitoring of carrier frequency, or to the optical control systems.
