Analog & Digital Electronics

Analog & Digital Electronics for GATE Electrical and Electronics Engineering, one topic per lesson: the theory in plain words, the formulas, a solved example, and GATE-style questions (MCQ, MSQ and NAT) whose numerical answers are recomputed by a program when the site is built.

Start the first lesson

1Analog Electronics

  1. Diodes, Rectifiers and RegulatorsPN junction diode characteristics and models, half-wave and full-wave rectifiers, average and RMS values, ripple factor, capacitor filters, clippers and clampers, and Zener regulators.
  2. BJT and MOSFET AmplifiersBJT operating regions and biasing, stability, small-signal hybrid-pi model, CE, CB and CC amplifiers, MOSFET characteristics, CS amplifier gain, frequency response and multistage amplifiers.
  3. Op-Amps, Feedback and OscillatorsIdeal op-amp rules, inverting, non-inverting, summing, difference, integrator and differentiator circuits, CMRR and slew rate, feedback topologies, Barkhausen criterion and RC and LC oscillators.

2Digital Electronics

  1. Digital Electronics for GATE EENumber systems, Boolean algebra and K-maps, logic gates and families, combinational circuits (adders, multiplexers, decoders), flip-flops, counters, shift registers, and DAC and ADC.
