ELECTRONIC DEVICE PROVIDED WITH FREQUENCY MULTIPLIER CIRCUIT, THE FREQUENCY MULTIPLIER CIRCUIT AND METHOD FOR MULTIPLYING SIGNAL FREQUENCY

摘要

PROBLEM TO BE SOLVED: To provide a multiplier circuit that is applied to data transfer and used according to a current mode logic(CML).;SOLUTION: The electronic device of this invention is provided with a periodic signal generator and a frequency divider circuit that multiplies frequencies of the periodic signals. The multiplier circuit consists of an exclusive OR gate that receives the periodic signal and of a frequency divider circuit connected between the input and the output of the gate. The frequency divider circuit can generate signals whose phases differ by 90° and the signals whose phases differ by 90° permit modulation of a type known as a name of 'zero demodulation'.;COPYRIGHT: (C)2002,JPO
