Electronic equipment containing a frequency multiplying circuitm a frequency multiplying circuit, and a procedure for multiplying signals

摘要

This electronic device comprises a periodic signal generator (12) and a frequency multiplier circuit (14) for multiplying the frequency of these periodic signals. This multiplier circuit (14) is made from a type gate "XOR" (20) receiving said periodic signals and a frequency divider circuit (22) connected between the output and an input of said door. Of this divider circuit, it is possible to derive easily the quadrature signals thereby making demodulation of the type known under the name of "0-demodulation".; Advantageously, this multiplier circuit (14) is designed as claimed in CML technology "Current Mode Logic". Application to the transmission of information.
