Question

Accepted Answer

A technical interview for Engineer Trainee covering topics such as CMOS, latch, flip flops, MOSFET, and dynamic memory.

CMOS stands for Complementary Metal-Oxide-Semiconductor and is a type of technology used in microprocessors and digital logic circuits.
A latch is a type of digital circuit that can store one bit of information.
The main difference between a latch and a flip flop is that a flip flop has a clock input and can store information for a longer period of time.
To make a metastable system stable, it is necessary to introduce a delay element or a feedback loop.
The V-I characteristics of a MOSFET describe the relationship between the voltage applied to the gate and the resulting current flowing through the source and drain.
Pinch-off is a phenomenon that occurs in MOSFETs when the voltage applied to the gate is high enough to create a depletion region that blocks the flow of current.
Dynamic memory is a type of computer memory that requires periodic refreshing to maintain its contents.
