week 3 Transistors, Logic Gates, and Combinational Logic

Question 1

what is a transistor?

Answer 1

made from a silicon

an electrical device that acts as an electrical switch.

Question 2

what is MOSFET

Answer 2

M: Metal 
O: Oxide 
S:semiconductor 
F: field 
E:effect
T: Transistors

used for switching or amplifying signals.

Question 3

what is nMOS

Answer 3

channel carries negative charges (electrons)

Question 4

what is pMOS

Answer 4

channel carries positive charges (holes)

Question 5

what is CMOS

Answer 5

pairing nMOS and pMOS transistors together

Question 6

what is an inverter?

Answer 6

logic gate that implements logical negation

Question 7

NAND gate

Answer 7

result of the negation of AND gate

Question 8

NOR gate

Answer 8

negation of the OR operator

Question 9

what is the gate delays

Answer 9

longest path in gates through a circuit

Question 10

PLA

Answer 10

Programmable logic array

a tool to go from truth table to logic gates

not the most efficient tool but it works.

Question 11

what is the half adder?

Answer 11

logic circuit implementing binary addition

Question 12

what is the combinational logic

Answer 12

using several logic gates together to create a logic circuit that performs work for us like adders, multipliers etc.
