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

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？
