A JFET Has the Following Ratings: VGSoff) = -2 V

question 31

Multiple Choice

A JFET has the following ratings: VGSoff) = -2 V to -5 V and IDSS = 4 mA to 12 mA. This device is being used in a self-bias circuit. When the bias line for the device is plotted, it is found that VGS for the circuit will have a range of -1 V to -2.5 V. What are the corresponding Qmin) values?

• A) VGSQ = -1 V, IDQ = 1 mA
• B) VGSQ = -2.5 V, IDQ = 250 μA
• C) VGSQ = -1 V, IDQ = 7.86 mA
• D) Cannot be determined with the information given.
