| 摘 要： | 介绍了一种可编程数字控制的移相原理,通过该原理可以设计一种精度可调的数字控制移相器。该原理主要通过一种倍频器倍频因子可调的方式来实现。文中设计的移相器可以在0~360°中达到任意度数的移相,其精度可以达到1°。并可通过精度控制输入信号,进一步提高精度。最后的仿真波形证实了这种原理的可行性。

| Abstract: | A programmable digital control phase-shift principle was described in this paper.It could provide us a kind of precisionadjustable digital control phase-shifter.And the principle was mainly achieved by a digital frequency multiplier whose multiplier factor could be adjusted.The phase shifter designed in this paper showed us a function that the phase could vary from 0 to 360 degrees with a precision of 1 degree.At the same time,further precision could be realized by the precision contol input signal.The ultimate simulation waveform in the paper proved the feasibility of the principle. |
