摘要: | Avalanche photodiodes (APDs) accompanied with the transimpedance amplifiers (TIAs) are often utilized as receivers in the communication system. A drawback of APDs is that the avalanche gain depends on temperature and varies with the bias voltage, leading to a decrease in the quality of communication. Moreover, the bias voltage for a high avalanche gain is up to 80 V, implying that a power module is inevitably required and raises the difficulty of integration. Therefore, a power management is proposed to provide an 80-V voltage and compensates the temperature dependence for a constant avalanche gain. The low-ripple high-conversion-ratio boost converter eliminates the LC resonance resulted from the nonideal effect of diodes to supress the output voltage ripple, implying that a high quality of bias voltage is guaranteed. Experimental results show that the output voltage ripple is 2.12 mV under the condition of 1-mA load current. A 97% accuracy of avalanche gain is proved to guarantee the high quality of APDs. |
