Combinational Logic Review
Combinational logic funstions are functions whose output value/s depend only on the current input values. They are typically expressed as Boolean functions, truth tables or logic gate networks. Common logic gates used are inverters (as discussed in previous lecture), AND gates, NAND gates, OR gates, NOR gates, etc. Static complementary gates are implemented using complementary (or dual) networks: a pull-up network (PUN) composed of PMOS transistors and a pull-down network (PDN) composed of NMOS transistors.
