通过施加规定的反向偏流,然后测量二极管两端的电压,即可测得反向偏置电流。
The drug ion is infused to tissue part by adding direct current bias to overcome the difficulty in achieving the deep tissue part of the oral and injected drugs.直流电导入药物离子,可以解决口服和注射药物难以到达的组织部位以及剂量不足的问题。
The current bias design: Taking advantage of the bandgap reference voltage, the temperature independent current bias for the system is designed by an operation amplifier.偏置电流源电路的设计:利用带隙基准电压源提供的,通过运算放大器为系统其他的模块提供一个与温度无关的稳定的电流偏置。
