Question
Referring to Fig. 11, if $V_{D D}=2 \mathrm{~V}$ for the varactor of Fig. 10, find the resonant frequency of the tank circuit if $C_{C}=40 \mathrm{pF}$ and $L_{T}=2 \mathrm{mH}$.
Step 1
From Fig. 11, we can see that when $V_{DD} = 2V$, the capacitance of the varactor is approximately $C_V = 60pF$. Show more…

For the "tank" circuit in Fig. $14.75,$ find the resonant frequency.
In the network in Fig. $\mathrm{P} 12.49$, the inductor value is $10 \mathrm{mH}$ and the circuit is driven by a variable-frequency source. If the magnitude of the current at resonance is $12 \mathrm{A}, \omega_{0}=$ $1000 \mathrm{rad} / \mathrm{s},$ and $L=10 \mathrm{mH},$ find $C, Q,$ and the bandwidth of the circuit.
(a) What is the resonant frequency of an $R L C$ series circuit with $R=20 \Omega, L=2.0 \mathrm{mH},$ and $C=4.0 \mu \mathrm{F} ?$ (b) What is the impedance of the circuit at resonance?
