Electronics & Communication Engineering roadmap

Analog & digital electronics, microprocessors, embedded systems, communication and VLSI.

Start with Basic Electronics, follow the steps in order, then build a project, prepare for interviews and earn your certificate.

Foundations

  1. Basic Electronics — Voltage, current, resistance and the laws that tie them. The foundation of every circuit: voltage, current, resistance and power; Ohm's and Kirchhoff's laws; systematic circuit analysis with RC, RL and AC phasors; and the network theorems that simplify complex circuits.
  2. Analog Electronics — Diodes, transistors, amplifiers and power. The devices and circuits that shape continuous signals: diodes, rectifiers and Zeners; BJTs, MOSFETs and JFETs; amplifiers and op-amps; feedback and oscillators; active filters; and linear and switching voltage regulators.
  3. Digital Electronics — From gates to flip-flops and converters. The logic behind every computer: logic gates and Boolean algebra, K-map simplification, combinational circuits (adders, multiplexers, encoders, decoders), sequential circuits (flip-flops, counters, registers), and analog-to-digital and digital-to-analog converters — with Verilog examples.

Core skills

  1. Microprocessors — Inside the CPU, from 8085 to ARM. How processors work and connect to the world: CPU architecture and performance, the classic 8085 and 8086 with assembly programming, the ARM architecture, interrupts, and memory and peripheral interfacing.
  2. Microcontrollers — Computers on a chip. Programming real microcontrollers: the classic 8051, AVR and PIC 8-bit families, ARM Cortex-M with STM32, the Wi-Fi/Bluetooth ESP32, and the register-level peripheral programming skills that carry across every vendor.
  3. Embedded Systems — Firmware that runs the physical world. Writing reliable firmware: Embedded C and C++, GPIO, timers and interrupts, serial buses (UART, SPI, I²C, CAN, LIN), ADC/PWM/DMA, real-time operating systems, bootloaders and device drivers.
  4. Communication Systems — Moving information through noisy channels. Analog and digital communication: system fundamentals and noise, AM, FM and PM, sampling and digital baseband, ASK/FSK/PSK and QAM, Shannon's capacity limits, and error detection and correction codes — with BER and coding simulations.

Advanced

  1. RF & Microwave — Waves, lines, antennas and radar. High-frequency engineering: RF fundamentals and link budgets, transmission lines and matching, antennas, waveguides, microwave devices and amplifiers, and radar systems from pulse radar to 77 GHz automotive FMCW.
  2. VLSI Design — From transistors to tape-out. How integrated circuits are designed: CMOS technology, digital and analog IC design, RTL with Verilog, SystemVerilog verification, FPGAs, synthesis and the ASIC flow, static timing analysis, physical design, and design for testability.
  3. Signal Processing — Understanding and shaping signals. The mathematics and practice of signal processing: signals and systems, Fourier series and transforms, Laplace and Z transforms, sampling and aliasing, digital FIR/IIR filters, and the DFT/FFT — with runnable Python examples.
