CASE ANALYSIS

Scenario

Generating a square wave oscillator using discrete components without integrated circuits.

Key decisions

  • Used two NPN transistors (Q1, Q2) with cross-coupled capacitors for regenerative switching.
  • Selected collector resistors (1k) and base bias resistors (22k) to ensure stable oscillation.

When to reuse this

When a simple, low-cost astable multivibrator is needed for clock signals, LED flashers, or PWM generation in hobbyist or educational projects.
