BIT-TRANSITION POINT EXTRACTION CIRCUIT AND INJECTION-LOCKED CLOCK RECOVERY CIRCUIT FOR NRZ-CODED SIGNAL AND METHOD FOR CONTROLING THE CIRCUIT

摘要

There is provided a bit-transition point extraction circuit device that includes: a predetermined current source transistor; a pair of transistors connected with a source which is biased to the current source transistor and is applied with a differential NRZ-recovery input signal from the outside; and a capacitor connected with the pair of transistors and the current source transistor so that a voltage of an output node of the current source transistor is constant.
