This paper deals with a differential delay cell based on the current division principle used for the implementation of a wide frequency range voltage controlled ring-oscillator. The frequency range is adjusted by controlling both the current flowing through the delay cell output and by the amount of delay cells used in the voltage controlled ring-oscillator.
