Draw the circuit diagram of differential instrumentation
amplifier and derive the expression of its output. Precisely
control of temperature in many industries is critical to ensure the
quality of the product. Discuss how you will use the
instrumentation amplifier using transducer bridge to measure the
temperature. Use block diagram to illustrate your concept.
a) Draw the simplest circuit of the nMOS co-source amplifier and
subtract the expression of the AC small signal voltage gain. (Note:
Drain will have RD and Source will have degeneration resistance
RS.)
b) Draw the small signal equivalent circuit of the circuit in
question (a). Find the expression of the output impedance.
c) What is the Miller effect?
My English is weak, please have a clean spelling.
a) Draw and label your own circuit diagram using standard
schematic symbols for a circuit with a 12 V battery, a 15 ohm
resistor, a 400 mH inductor, and a switch, all in series.
b) Write a diffferential equation (in the form of a loop
equation) describing the behavior of this circuit after the switch
is closed.
c) The switch is first closed at time t = 0. Write down an
equation for current in the circuit as a function...
5. a) Draw a state diagram for a sequential circuit that outputs
a 1 if and only if its single
input
has completed the sequence 1111.
b) Then build the circuit using D
flip-flops and any necessary gates. NO Overlap
is
Allowed.
6. Repeat question 5 but this time
OVERLAP IS ALLOWED:
Identify FM Broadcasting System in wireless communication and
design circuit.
Draw the appropriate circuit diagram or functioning
diagram.
Develop circuit diagram in MATLAB for FM Broadcasting System
and run the simulation.
2. About amplifiers:
(i) Draw/Project a circuit using an operational amplifier with gain
-100
(ii) What is the cutoff frequency of the amplifier in question (i)
if we used an operational amplifier 741?
(iii) What configuration (inverter or non-inverter) is most
vulnerable to finite CMRR ( Common Mode Rejection Ratio )?
(iv) Draw an instrumentation amplifier and calculate its literal
equation of the gain
Draw the electrical circuit diagram of electromagnetic forming,
label it neatly and explain how a thin cylinder can be expanded or
compressed by this process.
