The following sentence contains two personal pronouns in parentheses. Underline the pronoun that correctly completes the sentence. Then, on the line provided, write DO if the pronoun is a direct object, IO if it is an indirect object, or OP if it is an object of a preposition. Example $\underline{\text{IO}}$ 1. Mr. Graves offered Tranh and (I, $\underline{\text{me}}$) endless encouragement and guidance.

A CS amplifier operating with a $g_m$ of $2 \mathrm{~mA} / \mathrm{V}$ and having $r_o=20 \mathrm{k} \Omega$ has a $2-\mathrm{k} \Omega$ resistance $R_s$ connected in its source lead. Find the output resistance $R_o$. Recalling that the open-circuit voltage gain remains unchanged at $A_0$, find the gain obtained with $R_L=100 \mathrm{k} \Omega$.

In each sentence below, underline the correct pronoun in parentheses. Then, identify the function of the pronoun by writing above it $S$ for subject, $PN$ for predicate nominative, $DO$ for direct object, $IO$ for indirect object, $OP$ for object of a preposition, or $A$ for appositive.

Example 1. Our neighbors, (her, $\underline{\text{she}}$)(A) and Mrs. Stinson, are always thoughtful and pleasant.

15. Did your father write down the recipe for Matt and (her, she)?

An amplifier with an input resistance of $100 \mathrm{k} \Omega,$ an open-circuit voltage gain of 100 V/V, and an output resistance of $100 \Omega$ is connected between a $20-\mathrm{k} \Omega$ signal source and a $2-\mathrm{k} \Omega$ load. Find the overall voltage gain $G_{v}.$ Also find the current gain, defined as the ratio of the load current to the current drawn from the signal source.

Underline the noun clause in each sentence, and then, identify its function by writing above it S for subject, PN for predicate nominative, DO for direct object, IO for indirect object, or OP for object of a preposition.

Example 1. Do you know $\overset{\textit{\color{#c34632}{DO}}}{{\underline{\text{who the first female prime minister of India was}}}}$?

Gilbert taught whoever was interested the basic chess moves.

A CS amplifier has $C_{C 1}=C_s=C_{C 2}=1 \mu \mathrm{F}, R_G=10 \mathrm{M} \Omega, R_{\text {sig }}=100 \mathrm{k} \Omega, g_m=2 \mathrm{~mA} / \mathrm{V}, R_D=R_L=10 \mathrm{k} \Omega$. Find $A_M, f_{p 1}, f_{p 2}, f_{p 3}$, and $f_L$.

A CG amplifier when fed with a signal source having $R_{\mathrm{sig}}=100 \Omega$ is found to have an overall voltage gain of 12 V/V. When a $100-\Omega$ resistance was added in series with the signal generator the overall voltage gain decreased to 10 V/V. What must $g_{m}$ of the MOSFET be? If the MOSFET is biased at $I_{D}=0.25 \mathrm{mA},$ at what overdrive voltage must it be operating?

An ideal series-shunt feedback amplifier. Assume $R_S$ is negligibly small. (a) If $V_i=100 \mathrm{mV}, V_{f b}=99 \mathrm{mV}$, and $V_o=5 \mathrm{~V}$, determine $A_v, \beta_v$, and $A_{v f}$, including units. (b) Using the results of part (a), determine $R_{i f}$ and $R_{o f}$, for $R_i=5 \mathrm{k} \Omega$ and $R_o=4 \mathrm{k} \Omega$.

Find the value of the resistance $R_{e},$ which, when connected in the emitter lead of a CE BJT amplifier, raises the output resistance by a factor of (a) 5, (b) 10, and (c) 50. What is the maximum possible factor by which the output resistance can be raised, and at what value of $R_{e}$ is it achieved? Assume the BJT has $\beta=100$ and is biased at $I_{C}=0.5 \mathrm{mA}.$

In the following sentences, underline the gerund or gerund phrase. Then, identify its function in the sentence by writing above it S for subject, PN for predicate nominative, DO for direct object, or OP for object of a preposition.

Example 1. $\overset{\textit{\color{#c34632}{S}}}{{\underline{\text{Stargazing}}}}$ is a popular hobby among many people.

One other helpful activity is studying star charts to learn the layout of the sky.

D.M., a 25-year-old man, hops into the emergency department (ED) with complaints of right ankle pain. He states that he was playing basketball and stepped on another player's foot, inverting his ankle. You note swelling over the lateral malleolus down to the area of the fourth and fifth metatarsals, and pedal pulses are $3+$ bilaterally. His vital signs (VS) are 124/76, 82, and 18. He has no allergies and takes no medication. He states he has had no prior surgeries or medical problems. In assessing D.M.'s injured ankle, what should you evaluate?

An amplifier using balanced power supplies is known to saturate for signals extending within $1.2 \mathrm{~V}$ of either supply. For linear operation, its gain is $500 \mathrm{~V} / \mathrm{V}$. What is the rms value of the largest undistorted sine-wave output available, and input needed, with $\pm 5-\mathrm{V}$ supplies? With $\pm 10$ - $\mathrm{V}$ supplies? With $\pm 15-\mathrm{V}$ supplies?

An electric guitar has steel strings vibrating next to a small magnet and a 'pick-up' coil connected to an amplifier:

If you pluck the string so that it vibrates at a frequency of $500 \mathrm{~Hz}$,

a) what happens to the magnetic field near the coil?

b) what happens in the coil?

c) what do you hear?

Electric guitars can't use nylon strings. Why?

The circuit parameters of a diff-amp are $V^{+}=3 \mathrm{~V}, V^{-}=-3 \mathrm{~V}$, and $I_Q=0.15 \mathrm{~mA}$. The transistor parameters are $K_n=0.2 \mathrm{~mA} / \mathrm{V}^2, V_{T N}=0.4 \mathrm{~V}$, and $\lambda=0$. Determine the value of $v_d=$ $v_{G 1}-v_{G 2}$ that produces (a) $i_{D 1}=0.2 I_Q$, (b) $i_{D 2}=0.8 I_Q$, and (c) $i_{D 1}=I_Q$.
