Question

Assuming an ideal op-amp find the 3ds frequency of the circuit, if R1-1.7 KA, R2-112 KA, R3:20 KQ, and C-5 nf, HH but с Answer radi w R2 w R1 Vw vo R3 Oton 10 Consider the above circuit with the component values: 11.7KO, R2112 KOR320 KO and Co. Find the DC gain of the circuit Consider the above circuit with the component values 1.770,000 in the other teretanin degrees 100

Answer 1

here is the answers:-

Question 9:-

3db frequency:-

3db frequency is also called as cutoff frequency

3db frequency $=\frac{1}{2\Pi R_{2}C}$

$=\frac{1}{2\Pi(11.2\times 10^{3})\times (5\times 10^{-9}) }$

3db frequency = 2842.05 Hz

Question 10:-

DC gain of the circuit = 20log( R_f / R) - 3 db

= 16.37 - 3

DC gain of the circuit = 13.37 dB
