a. 5v mos design current能小到多小啊?
1. Low power opa . Bias current use 1na , 0.5na mos current miiror 可以吗? 2. Low power osc , 1Khz osc , 用 0.5na 充电容做 很低频 r-c osc , 用比较器比电压 3. Low current bandgap . 有没 10na 下能工作 bandgap vbg=1.1v vdd = 1.8~ 5v
b. 1.8v lv mos design
0.1 na mos current miiror 可以吗?
bulk cmos process 0.18um , no SOI process
A Novel Ultra Low Power High Performance Atto-Ampere CMOS Current Mirror with Enhanced Bandwidthnovel CMOS atto-ampere current mirror (AACM) is proposed which reaches the minimum yet reported current range of 0.4 aA
