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。
programmable digital control phase- shift principle was described in this paper. It could provide us a kind of precision-adjustable 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.
