Describe the operation of an OPAMP-based oscillator using the
concept of a basic oscillator feedback circuit. Your description
must include all pertinent equations relating the overall closed
loop gain and the open-loop and feedback gain
Use a 5 nF capacitor to design a series RLC bandpass filter, as
shown at the top of Fig. 14.27.The center frequency of the filter
is 8 kHz, and the quality factor is 2.
a) Specify the values of R and L.using pspice
b) What is the lower cutoff frequency in kilohertz? using
pspice
c) What is the upper cutoff frequency in kilohertz?using
pspice
d) What is the bandwidth of the filter in kilohertz?using
pspice
Design the component values for the series RLC bandreject filter
so that the center frequency is 5 kHz and the quality factor is 5.
Use a 500 nF capacitor.
Important: Please.....Plot the circuit of your
design, marking the output voltage. I think it means
a sinewave on an X, Y, graph plot with vo as X, and
t(ms)>0 as Y. Is this possible here?
Design an analog-digital converter circuit with OpAmp that
receives a 5 Vp sinusoidal signal and a 3.5 V trip level as input.
It must deliver a TTL (Low / High) signal as output.

how to design a butterworth filter based on magnitude. Please
give a numerical example. Assume only passband frequency and
magnitude level is given, nothing else at all.
A bandpass series filter has parameter values of R=150Ω , C=2μF
and
L=3mH . The filter is energized with a voltage source which has
an
internal resistance equal to 100Ω.
Using Matlab, write a code to print Bode magnitude plots for the
filter transfer function by
itself and the transfer function of the filter modified by the
source resistance?
why is important to consider matching in the design of a ring
oscillator? What if one were to neglect matching? What impact would
it have in a commercial product?
