Question 4
a) Explain the operation of a CMOS transmission
gate, illustrating the component symbol, MOS transistor circuit and
function table. [3 marks]
b) Draw the XNOR (F = (A.B + A.B) logic circuit
implemented using
CMOS transistor-based logic.
CMOS transmission gates.
Compare the transistor count for each implementation. [4
marks]
c) Draw and label a CMOS transmission gate
circuit for a 4-to-1 multiplexer, using the following signal
names:
sel(1:0) input data path select signal
muxIn(3:0) 4 x 1-bit input...
1 Explain the meaning of the term mutarotation.
2 Draw the structure of a disaccharide made up of two D-glucose
units. The glycosidic bond is
α-1,6-glycosidic bond.
3 Trehalose is a disaccharide that can be obtained from fungi,
sea urchins and insects. Acid hydrolysis of
trehalose yields only D-glucose. Trehalose is
hydrolysed by α-glucosidase and not by β-glucosidase
enzymes. Methylation of trehalose followed by
hydrolysis yields two molar equivalents of
2,3,4,6-tetra-O-methyl-D-glucopyranose.
From the following experimental data,...
a) In your own understanding draw a static PMOS and NMOS structure
transistors
and explain how each operates as switch , illustrate your
explanation with sketches.
b) Design a two way NOR Simple static CMOS Circuits , Explain the
circuit topology
and its operation
c) At your level in the field of Electronics and electrical
engineering ,draw the various
Field effect transistor (FET) possible configurations, In your own
word and
understanding briefly analyze each configuration
Draw the figure for memory segments with 8086 microprocessor
software model. Explain the logical address structure used for each
segment (Explain which registers are used in logical address
presentation of each segment; segment address : offset
address).
