Q1. What are flip flops and latches
Ans. 
Flip flops and latches are sequential logic circuits used in digital electronics to store and transfer data.
• Flip flops are clocked circuits that store one bit of data, while latches are level-sensitive circuits that store data as long as the enable signal is active.

• Flip flops are edge-triggered, meaning they change state on a clock edge, while latches are level-triggered, changing state as long as the enable signal is ...read more

Q1. What kind FPGAs used, tell me difference
Ans. 
FPGAs are Field-Programmable Gate Arrays used in hardware design. They can be categorized as SRAM-based, Flash-based, or Antifuse-based.
• SRAM-based FPGAs are volatile and require reprogramming every time they power up. Examples include Xilinx Virtex series.

• Flash-based FPGAs are non-volatile and retain their configuration even when powered off. Examples include Actel ProASIC3 series.

• Antifuse-based FPGAs are OTP (One-Time...read more

Q2. Calculation of Decoupling analysis
Ans. 
Decoupling analysis involves calculating the required capacitance to maintain stable voltage levels in a circuit.
• Decoupling analysis is essential for ensuring stable power supply in electronic circuits.

• It involves calculating the amount of capacitance needed to filter out noise and maintain voltage levels.

• Decoupling capacitors are placed strategically in a circuit to provide this filtering effect.

• The formula for calcul...read more
