Summary[edit]
DescriptionNeon bulb relaxation oscillator hysteresis curve 2.svg |
English: The IV curve (characteristic curve) of a neon bulb relaxation oscillator (top) showing the hysteresis loop (abcd) of the oscillation, and the resulting output voltage waveform (bottom). A neon bulb relaxation oscillator consists of a capacitor which is charged from a voltage source V0 through a resistor R2, with a neon bulb across the capacitor which discharges it once it reaches the bulb's breakdown voltage Vb. Ths hysteresis curve (abcd) shows the detailed cycle:
The circuit generates a sawtooth wave, (bottom) alternating between Ve and Vb. The center blue line is the load line, with a slope equal to the resistance R2. In order for the circuit to oscillate, the load line must intersect the IV curve in it's negative resistance region (red) the segment from b to d, where it is declining to the right:
