Oscillators Collection

The Oscillators Collection is a set of educational circuit boards designed to support first- and second-semester electronics courses focused on analog circuit design and oscillator operation.

This collection includes eight foundational oscillator configurations:

• Colpitts Oscillator
• Hartley Oscillator
• Phaseshift (Biased Low) Oscillator
• Phaseshift (Biased High) Oscillator
• Three Phase Sinewave Generator
• Single Transistor Oscillator
• Two Transistor Oscillator
• Adjustable Relaxation Oscillator (Opamp)
• Adjustable Relaxation Oscillator (Transistor)

Each circuit is implemented as a standalone miniPCB™ with standardized layout, clear labeling, and accessible test points for easy integration into lab environments. These boards are ideal for reinforcing key learning outcomes such as feedback principles, waveform generation, frequency control, and timing behavior in analog circuits.

Instructors can use the full set to guide students through progressive exploration—from basic two-transistor oscillators to more advanced op-amp and feedback-based designs—while observing waveform behavior, frequency control, and stability through real-world measurements.
