摘要：

A simple sine wave oscillator delivering two signals in quadrature has been developed, covering the frequency range from below 1 Hz to 100 MHz and being voltage-controllable over each frequency decade. The circuit consists of two 90-degrees phase shift stages using active allpass filters and an inverter, all arranged in a feedback loop. Although general application is envisaged, the design is particularly suitable in particle electrorotation studies.
