Q2. What are the advantages of the complementary CMOS logic circuit?
The advantages of the complementary CMOS logic circuit are stability and layout regularity at lower voltages due to smaller number of interconnecting wires and complementary pairs of transistors.
Q3. What contributions have the authors mentioned in the paper "Comparative performance analysis of xor-xnor function based high-speed cmos full adder circuits" ?
Abstract— this papers presents the realization of full adder designs using Complimentary CMOS Design, Complimentary Pass Transistor Logic Design and XOR-XNOR Design in a single unit. The main motive of this paper is to determine the comparative study of power, delay, power delay product ( PDP ) of different Full adder designs using CMOS Logic Styles. The XOR-XNOR implementation provides better performance and requires less number of transistors compared to other full adder designs.
Q4. What are the reasons for the power dissipation in CMOS circuits?
There are four reasons for the power dissipation: dynamic power due to the charging and discharging of capacitance in the circuit because of switching transactions and leakage current is because of reverse bias condition in diode structures, sub threshold leakage, short-circuit current power due to rise and fall times, and static biasing power found in some logic styles (i.e pseudo-NMOS)
