Unformatted text preview: c. State the approximate expression for the no—Ioad voltage gain, AV and state the condition for the approximate expression to be valid. Using this approximate expression, calculate the required value for RD to obtain AV = -10. Check if the condition for using the approximate expression is met. [2 marks] DC Analysis — Biasing Design d. Calculate the quiescent drain current, IDQ, given VGSQ = 8.2 V. [2 marks] e. Determine the bias line equation of the network by determining the expression for the DC gate-source voltage, VGS in terms of V0 , ID and Rs. [2 marks] f. With the quiescent values found for IDQ ad VGSQ , calculate VG using the bias line equation, assuming R5 = 1 k9. [2 marks] 9. State the expression for the DC gate voltage, VG in terms of VDD, R1 and R2. Using the value found for V0, determine suitable values for resistors R1 and R2 in the MS) range. _ [2 marks] ...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
