Introduction to CMOS inverter
CMOS: CMOS stands for Complementary Metal Oxide Semiconductor Field Effect Transistor. Fig: CMOS circuit Advantages of CMOS: High noise margin due to full voltage swing. High input impedance due to I G = 0. Low output impedance, in steady state there always exists a path with finite resistance between output and either V DD or GND, making it less sensitive to noise and disturbances. Ratio less property as the logic of the CMOS does not depend on the W/L ratio of P and N MOSFET. Zero static power dissipation as no direct exists between ground and supply rail under steady state condition. The analysis of the gate is done with respect to the different design metrics as listed below: Cost, expressed by the complexity and area. Integrity and robustness, expressed by the static (or steady-state) behaviour. Performance, determined by the dynamic (or transient) response Energy efficiency, set by the energy and power consumption. Logic: Positive logic = 1: positiv...
