Abstract
A voltage-controlled ring oscillator based on feedback derived from a weighted sum of two phases of an oscillation is described. A prototype fabricated in 1-μm CMOS attains a maximum frequency of 320 MHz, with a controllable frequency range of 100 MHz. An almost sinusoidal waveform appears at the output across this range of frequencies
