what is CMOS inverter explain its funtionality?what is body bias effect? why MOS why not BJT? timing anylsis question

Question

Accepted Answer

CMOS inverter is a digital logic gate that converts input signal to its complementary output signal.

CMOS inverter consists of a PMOS and an NMOS transistor connected in series.
When input is high, PMOS is off and NMOS is on, output is low.
When input is low, PMOS is on and NMOS is off, output is high.
Body bias effect is the change in threshold voltage of MOSFET due to variation in body voltage.
MOSFET is preferred over BJT due to its low power consumption and high input impedance.
Timing analysis involves calculating the delay of the circuit and ensuring proper timing constraints are met.
