Question 28 Not complete Marked out of 6.00 What is the low frequency input resistance, Ri,...
What is the low frequency input resistance, Ri, in for the amplifier shown at 27° C with Rd = 31.3612, Rs = 1.2k and Rg = 5.750 ? Use: W/L = 18, Id = 870 A, VTP = -0.5V, k'n = 40A/V^2. Neglect the effect of channel-length VOD VBIAS + RG Vi modulation and body effect. RS M1 Vo R. R RD Answer: Check
All questions refer to the "simplified" CE amplifier shown below that has no RE at all, and no Cg. There is also no CL. The bias circuit gives Ic 1.5 mA The transistor has B 120, ro 50 k, Cu 1.5 pF and C 9 pF. You can neglect r.

Sketching relevant output (Vc-Ic) characteristics that decide Q-point coordinates and DC load-line details (of the NPN-BJT/Si circuit of Fig. 9 of Circuit X) Further, establish an appropriate AC-load line and decide the maximum swing of the output voltage across Rload with respect to the Q-point. Assume the input...
