Title: Modulation circuit using dds
Inventor: MATSUURA YUJI
IPC: H03B28/00
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To provide both functions of FSK modulation and waveform offset by correct modified waveform characteristics for a synthesizer with fast locking operation by controlling the DDS by a control signal so as to execute the FSK modulation and waveform offset a synthesizer output. SOLUTION: The output of a reference oscillator 1 is divided into ten outputs by a frequency divider 2 to output to a phase comparator 3 as a high probability reference signal. On the other hand, the high frequency output of VCO6 is fetched to an outside as the synthesizer output and a part of the output is fed back, made a sine wave by lowering its frequency to the handleable frequency of DDS 8 by a frequency divider 7 and inputted to the comparator 3 through a frequency divider 11. This and the output of a frequency divider 2 are phase-compared with each other to control the frequency of VCO6 to be higher when the former is delayed and to be lower when the former is advanced by a charge pump 4.  As the result of this, the output of the pump is in the locking state of high impedance except the moment of repeating the correction of the slight deviation of the phases of both of them and the divider 11 is precisely controlled to be 1 MHz.
