Keywords:sinusoidal oscillator,iteratively terminated amplifier,SPICE

To design a frequency variable Twin-T oscillator based on SPICE, we analyze an iteratively terminated amplifier, which has an opened Twin-T feedback loop of the oscillator. We demonstate that the technique is useful for harmonic oscillator design.
