ENGR-434 Homework #1 - Due Monday 4/08/19
Do these chapter 1 problems: 1.6b, 1.7d, 1.8, 1.15, 1.17a,b,c
As you do these, please don't google for a solution. The
value of problems comes from exercising your own intelligence
(you have a great deal of that) and thereby growing your ability.
Note that for the compound gate problem (1.6b) the output is asserted
low. And note that problem 1.7d is asking for a combination of gates
to solve it, not a transistor solution.
For problem 1.17 use the lambda design rules as defined in section 1.5.3
when doing the stick diagram. Calculate the required area in units of
square lambda.
I approach compound gate problems by first designing the pull-down
network using N channel MOSFets (noting that if an input signal is
high then it is active and the N device will be turned on). Once
the network of N devices is established the P device network is
basically the complement, i.e. inputs connected to series N devices will
connect to parallel P devices and inputs connected to parallel N devices
will now connect to series P devices.
