| 技術摘要 / Our Technology： |
一種具有三角積分調變之相位旋轉器之頻移鍵控器，包含鎖相迴路，用來產生壓控訊號；多相位產生器，用來接收該壓控訊號並據以產生N個具有相同頻率之相移訊號，該N個相移訊號中之任二相鄰者間均具有相等之相移量；三角積分調變器，用來接收發射資料，並依據該發射資料以調變時脈隨機地輸出調變位元；以及相位旋轉器，用來接收該N個相移訊號，並依據該三角積分調變器所輸出之調變位元選擇性地輸出該N個相移訊號及除頻訊號中之一者，該除頻訊號之頻率為該N個相移訊號中任一者之頻率的( )分之一。
A frequency shift keying modulator having sigma-delta modulated phase rotator is disclosed, which includes a phase-locked loop for generating a voltage-controlled signal; a multi-phase generator for receiving the voltage-controlled signal and generating N phase-shift signals having same frequency according to the voltage-controlled signal, the N phase-shift signals having a same phase shift between the phase-shift signals adjacent to each other; a sigma-delta modulator for receiving transmission data and randomly outputting a modulation bit at a modulation clock according to the transmission data; and a phase rotator for receiving the N phase-shift signals and selectively outputting one of the N phase-shift signals and a frequency-divided signal according to the modulation bit, wherein the frequency of the frequency-divided signal is
1 / ( 1 + n N )
of the frequency of any one of the N phase-shift signals.
