CS302 CURRENT MIDTERM PAPER


What is the role of MOS transistor in Mask ROM?

How many input and output bits do a Half-Adder contain?

How can a PLD be programmed?

DRAW THE CIRCUIT DIAGRAM OF GATED S-R LATCH.?

Name the three declarations that are included in “declaration section” of the module that is created when an Input (source) file is created in ABEL?

Explain with example how noise affects Operation of a CMOS AND Gate circuit?




GIVEN THE FOLLOWING STATEMENT USED IN PLD PROGRAMMING:
Y PIN 23 ISTYPE ‘COM’;
Explain what does this statement mean?

VARIABLE Y AT OUTPUT PIN 23 WHICH IS A COMBINATIONAL OUTPUT AVAILABLE DIRECTLY FROM THE AND-OR GATE ARRAY OUTPUT.

Y = VARIABLE Y
PIN 23 = PIN NUMBER 23
ISTYPE “COM” = OUTPUT TYPE COMBINATIONAL
