3. Introduction
• Digital Electronics is that branch of electronics
which deals with the digital signals to perform
various tasks and meet various requirements .
• It is based upon the digital design
methodologies and consists of digital circuits,
IC’s and logic gates.
• It uses only binary digits.

4. Need for Digital Electronics
• Most analog systems were less accurate and
were slow in computation and performance.
• Digital system have the ability to work faster
than analog equivalents.
• It was much economical than analog
methodologies as the performance was faster.

5. Logic Gates
• Logic gates are the basic blocks of the digital
circuits.There are basic gates of three types
viz. AND, OR & NOT.
• Two universal gates are made of these 3 basic
gates, which are NAND gate & NOR gate.
• These are the sub- components of the IC’s .

7. Integrated Circuits
• IC’s are the micro circuits which are fabricated
on a very small silicon wafers (chip) at which
various components like BJT, CMOS etc.,
• These days, various types of circuit
integrations are possible such as small scale,
large scale, and very large scale integration
(VLSI).

8. IC implementation
• IC is produced using VLSI by two
technologies.They are:
Application Specified Integrated Circuit
Field Programmable Gate Array

9. ASIC Vs FPGA
ASIC
• Used for particular
Application.
• Static Structure
• Digital or Mixed Signal
• High NRE
• Low Cost
FPGA
• Application of the IC can be
modified
• Reprogrammable Structure
• Primarily Digital
• No NRE
• High Cost

10. Conclusion
• I Conclude that, FPGA is the newest
technology of implementing Ics.It is antype of
gate array.
