JNTU B.Tech in Electronics and Instrumentation Engineering-Digital IC Applications Ex

Will you please provide me the previous year Question paper of Jawaharlal Nehru Technological University - JNTU for B.Tech in Electronics and Instrumentation Engineering-Digital IC Applications Exam???

Here I am sharing the previous year Question paper of JNTU for B.Tech in Electronics and Instrumentation Engineering-Digital IC Applications Exam

1. (a) What are the parameters that are necessary to define the electrical charac-
teristics of CMOS circuits? Mention the typical values of a CMOS NAND
gate.
(b) Design a CMOS 4-input AND-OR-INVERT gate. Draw the logic diagram and
function table.

2. (a) Mention the DC noise margin levels of ECL 10K family.
(b) A single pull-up resistor to +5V is used to provide a constant-1 logic source
to 15 different 74LS00 inputs. What is the maximum value of this resistor?
How much high state DC noise margin can be provided in this case? [6+10]

3. (a) Write a VHDL Entity and Architecture for a 3-bit synchronous counter using
Flip-Flops.
(b) Explain the use of Packages. Give the syntax and structure of a package in
VHDL.

4. Design a logic circuit to detect prime number of a 5-bit input. Write the structural
VHDL program for the same.

5. Design a 10 to 4 encoder with inputs 1- out of ?10 code and outputs in BCD?
Provide the data flow style VHDL program?

6. Write VHDL program for 1-bit comparator circuit with the input bits and equal,
grater than and less than inputs from the previous stage and the outputs contain
equal, greater than and less than conditions. Using this entity write VHDL program
for 16-bit comparator using data flow style. Do not use any additional logic for this
purpose.

7. (a) Differentiate between ripple counter and synchronous counter? Design a 4-bit
counter in both modes and estimate the propagation delay
