Q1. Cpp pointers explain smart pointers
Ans. 
Smart pointers in C++ provide automatic memory management and help prevent memory leaks.
• Smart pointers are objects that manage the memory of a pointer automatically.

• They ensure that memory is deallocated when it is no longer needed.

• Examples include unique_ptr, shared_ptr, and weak_ptr.

Q1. Proof of Regions of operations of Mosfets in CMOS inverter.
Ans. 
The regions of operation of MOSFETs in a CMOS inverter are cutoff, triode, and saturation.
• MOSFET operates in cutoff region when Vgs < Vth

• MOSFET operates in triode region when Vgs > Vth and Vds < Vgs - Vth

• MOSFET operates in saturation region when Vgs > Vth and Vds > Vgs - Vth

• CMOS inverter uses both NMOS and PMOS transistors to achieve high noise immunity and low power consumption

Q1. Explain the power leakage and dynamic power in CMOS circuits.
Ans. 
Power leakage is the power dissipated in CMOS circuits when transistors are in off state, while dynamic power is the power dissipated during switching.
• Power leakage occurs due to subthreshold leakage currents in transistors when they are in off state

• Dynamic power is the power dissipated during charging and discharging of capacitive loads in CMOS circuits

• Power leakage increases with decreasing transistor size, while dyn...read more
