Transcripts
hello everyone welcome to the video
lecture series of integrated circuits
and we were studying about digital
integrated circuit design
latches and flip flops which is unit 4th
subject code is kec501 so
we were discussing about the various
boolean expression and the cmos logic
design and in the last lecture we have
seen the cmos logic design for
xor and xnor now in today's lecture we
will see the cmos logic design for nand
gate as well as
or gate so first of all uh first one is
uh and gate which is a boolean
expression for and gate is y
is equal to a dot b so this is the
expression for
and gate
between
this
output and operation right
so this is how we can design a cmos
logic design for
and get similarly uh we can design the
cmos logic for
or gate so in the next page we will see
this uh or gate
okay now
it will be a plus b bar
right so this is how we can design cmos
logic circuit designing for
your and gate as well as for the uh or
gate so if you have
any query about these two gates you can
post your
questions in the comment box thank you
so much
