摘要
采用数字合成技术制作了三相正弦波信号发生器 ,其波形采用 3个加权电阻网络和高速CMOS开关数字合成 ,精确保证 3个正弦波之间的相位差为 12 0° ,产生的信号具有极好的幅值、稳定的频率、小失真和高达 3.
A three-phase sine-wave signal generator is designed using digital synthesis method. The wave form is digitally synthesized using three weighting resistor networks and high-speed CMOS switches. The phase differences among the three sine-waves are kept precisely at 120°. The signal has excellent amplitude, frequency stability, small distortion and a wide frequency range up to 3.3 MHz.
