Description: 
"基本恒流源电路图" 
"	对恒流电路的主要要求有：" 
"	1、等效微变电阻要大。" 
"	2、温度变化时的稳定性要好。" 
"	3、器件参数，正向压降变化时，电流的恒定性要高。" 
"	4、在特殊情况下，要求电流值可以控制。" 
"	构成恒流电路的基本方法是利用三极管的集电极电压对电流的影响小，再加电流负反馈提高输出电流的恒定性，在必要时，还采用特殊电路进行温度补偿。" 
"" 
"	BG1和BG2的基极和发射极分别连在一起，所以两管的VBE总是相等的。当两管的参数相等时，它们的集电极的电流（即恒流源的输出电流）与基极电流IB也是分别相等的。" 
"	若BG1管的集电极电流Io就是恒流源的输出电流，Ir是参考电流。改变Ir，Io就跟着变。Io如同Ir的镜象，所以此电路叫做镜象恒流源。"
