Question
Calculate the gain with and without feedback for an FET amplifier as in Fig. 7 for circuit values $R_{1}=800 \mathrm{k} \Omega, R_{2}=200 \Omega, R_{o}=40 \mathrm{k} \Omega, R_{D}=8 \mathrm{k} \Omega$, and $g_{m}=5000 \mu \mathrm{S}$.
Step 1
First, we need to find the voltage gain without feedback (Av). For this, we can use the formula: Av = -gm * RD where gm is the transconductance and RD is the drain resistance. Show more…

A noninverting current amplifier is portrayed in Fig. $5.92 .$ Calculate the gain $i_{o} / i_{s} .$ Take $R_{1}=8 \mathrm{k} \Omega$ and $R_{2}=1 \mathrm{k} \Omega$
(a) For the circuit shown in Fig. $5.53,$ show that the gain is $$\frac{v_{o}}{v_{i}}=-\frac{1}{R}\left(R_{1}+R_{2}+\frac{R_{1} R_{2}}{R_{3}}\right)$$ (b) Evaluate the gain when $R=10 \mathrm{k} \Omega$ $R_{1}=100 \mathrm{k} \Omega, R_{2}=50 \mathrm{k} \Omega, R_{3}=25 \mathrm{k} \Omega$
