Title:
FEED-FORWARD RING OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2011/007944
Kind Code:
A1
Abstract:
Disclosed is a feed-forward ring oscillator. The feed-forward ring oscillator according to the present invention comprises of: a plurality of delay cells for outputting differential output signal couples by receiving first differential input signal couples and second differential input signal couples. The feed-forward ring oscillator is characterized in that the delay cells are connected in a shape of a ring, each of the delay cells includes a differential output signal couple of the delay cell in the previous stage as a first differential input signal couple, the differential output signal couple of the delay cell in the two previous stages as a second differential input signal couple, and each of the delay cells is configured using multiple independent gate field effect transistors. According to the present invention, an occupied area is reduced and an integration of circuits is improved by decreasing the number of elements for configuring the delay cells using the multiple independent gate field effect transistors.
