The slope obtained in VGSvs ID was 0.002. What is the value ofgm?(a) 1(b) 2(c) 0.002(d) 0I had been asked this question during an online interview.I'd like to ask this question from The FET Small-Signal Model topic in section Field-Effect Transistors of Electronic Devices & Circuits

Answer»

The CORRECT option is (c) 0.002

The EXPLANATION is: gm = CHANGE in drain CURRENT/ change in gate to source voltagegm = slope of VGSvs IDgm = 0.002.
