摘要:

为解决雪崩光电二极管正常工作时需要的直流反向偏压问题, 提出了利用电感式升压电路的设计方法。该方法利用开关管、 单电感、 电容、 电阻对5 V直流电进行升压, 结合555芯片组成的压控振荡器产生频率信号, 控制开关管的导通与关断, 并利用反馈电路控制压控振荡器的频率, 同时采用Multisim9进行仿真。仿真结果表明, 当输入电压为5 V时, 输出电压为160.096 V且保持稳定不变, 解决了雪崩光电二极管在正常工作时需要在阴极加上很高直流反向偏压的问题。

Abstract:

To ensure the high sensitivity of detector, inductive booster circuit design method is proposed. The method uses the switch tube, single inductor, capacitance, resistance to step up for 5 V dc, the VCO(Voltage-Controlled Oscillator) is composed of 555 chip to produce the frequency of the VCO. The computer simulation analysis method is used by Multisim9, the simulation results show that when input is 5 V, output is 160.096 V to keep stable. It solved the problem that the avalanche photo diode needs high dc reverse bias in normal work at the cathode.

Key words: avalanche photo diode (APD), detector, boost circuit, simulation
