Hi-fi audio amplifiers are usually built as discrete operational amplifiers with a relatively large gain (g ? 500) and with feedback that reduces the closed-loop gain to a smaller value k = 32. Since loudspeakers predominatly act like a resistor (nominal impedance: 8 ) with an inductor in series, the feedback network can be used to improve the frequency response in the audio range up to 20 kHz. We are primarily concerned with gain and frequency response of the amplifier....
Design a Sallen-Key circuit as shown in Figure 7.1. Choose component values so that the circuit produces a critically damped response (?? = 1/2) and a resonant radian frequency of ??0= 2000?? rad/sec (??0 = 1kHz). Be sure to choose component values that are available to you in your lab kit. You will not be able to exactly achieve the design goals with the restrictions of the component values, but you should try to get as close as possible with...
