回复 2# abab1394
我看hspice说明,
1、Area multiplying factor that affects the BETA, RD, RS, IS, CGS, and CGD model parameters. Default=1.0, in units of square meters.
它的单位是平方米?感觉怪怪的,这得多大啊?
2、后面有个举例:Example 2
In the following Jopamp1 JFET element:
Jopamp1 d1 g3 s2 b 1stage AREA=100u
◾The drain connects to the d1 node.
◾The source connects to the g3 node.
◾The gate connects to the s2 node.
◾1stage references the JFET model.
◾The area is 100 microns.
请问area的单位怎么理解呢? |
