An oscillator circuit is provided with delay cells having supply voltage terminals and being interconnected in a ring for providing a first oscillator signal. If the delay cells have supply voltage terminals in common a second oscillator signal can derived from the respective common supply voltage terminals. The first ring oscillator signal, which is possibly available in quadrature, has a low frequency providing a low power consumption to the oscillator circuit. The two highly sinusoidal oscillator signals are generated simultaneously and have a frequency, whose ratio depends on the number of delay cells in the oscillator circuit. The oscillator circuit can be easily implemented on a limited chip area for application in transmitters/receivers operating in the GHz range.
