Vlsi Hardware Interview Questions and Answers

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 impedanc...read more
