4. Is it possible to get a gain less than unity using a non-inverting amplifier configuration? If yes, sketch a circuit.

Question 7) Design a JFET amplifier network with ldss-8 mA, Ve=-4 V, R1=110 MN, R2=10 MQ. When an input AC signal V=10 mV is applied to the network, an output signal Vo=2V AC is obtained. (suppose that ra2 10R0) a) Draw the JFET amplifier network you prefer to design, and explain why you choose this network b) Explain the aims and reasons in using of all the peripheral components handled on your network c) Draw AC equivalent re model of the network (5p.) d) Draw transfer characteristic curve and derive lda and Vasa values from the characteristic curve e) Calculate Av, gm, VoD, Ro, Rs, Z; and Zn. Note: Please, do not forget using resistors and capacitors as peripheral elements whatever required for your complete design in the question (i.e. input, output terminals etc.)

For amplifier design, consider a very large load resistance RL . Use a 15 V DC source and a sinusoidal input signal of 200 mVpp and 1 kHz.   Hint: you can start by choosing a collector (Icq) or drain (IDQ) operating current between 5 mA and 10 mA. 1. Design an input stage with a common drain amplifier that complies with thefollowing specifications:  Voltage gain greater than or equal to 1 (Av1 ≥ 1). Input impedance greater than or equal to 250 kΩ (Zi1 ≥ 250 kΩ). Output impedance less than or equal to 2 kΩ (Zo1 ≤ 2 kΩ). Low cut frequency less than or equal to 20 Hz (fcb1 ≤ 20 kHz).   Use a 2N3819 (NTE312) transistor.
