    hierachy design in vlsi

    hierarchical design is used to reduce complexity of circuit by chip designer mainly three approach are used 1)modularity 2)regularity 3)locality 1)modularity - submodule have well defined function and Interface 2)regularity - big system divide into similar submodule Q- I have searched on...

    transistor sizing for AND gate?

    ok Nmos W/L=3/2 and Pmos W/L=6/4( transistor in inverter circuit) caseI - when to mosfet in series this is similar to one transistor with double length and same width Example two series nmos with W=1 and L=1 resultant W/L=1/2 case II when to mosfet in parallel W will be double with same L...
