Given:
Vcc = 3.6V, Iref = 1uA
Design Goal:
To obtain a 10uA output current to drive the Rload. The Rload CAN change from 10 ohms to 300K ohms. With the variation of Rload, the output current need to be maintained in 10uA with the variation of less than +/- 5%.
答 1: a design of current mirrorthis is the current
how to continnue to do it

答 2: 要求帮助？3.6V/0.3MΩ=12μA
电源电压太低，作为电流输出而言，我觉得不太可能满足你10μA的要求。
不知道理解错了没有？
