Title:
リングオシレータ、検出器、受信器及び情報キャリア再生装置
Document Type and Number:
Japanese Patent JP4231294
Kind Code:
B2
Abstract:
The ring oscillator has a closed chain of two modules. The modules (1, 2) have a primary (10) and a secondary amplifier stage (11) and a combiner (12) for combining output signals of the primary and the secondary amplifier stage so as to generate an output signal of the module. The amplifier stages have a mutually different delay, the primary and the secondary amplifier stage each being coupled to an input (13) of the module. The ring oscillator has a control unit (4) for generating two auxiliary control signals for controlling the amplification of the primary amplifier stage and the secondary amplifier stage in response to an input control signal (Co) representative for a desired frequency for the ring oscillator. An independent claim is included for a data and clock recovery unit, a receiver, an a device for reproducing an information carrier.
