D類放大器由於有較高的必v效益,因此近年來逐漸的備受重視,然而由於是切換式的操作,因此D類放大器比起傳統的線性放大器,其線性度是需要改善的目標,本論文提出一個以新型具有兩個比較點的遲滯視窗(Hysteresis Window)Bang-Bang Control調變技術為基礎的D類放大器(Class D Amplifiers)電路,具自我調準(self-tune)的輸入結構,使得電路在遲滯視窗的方面可以表現較良好,並且使用自我震盪(self-oscillation)的電路架構而不需要額外載波信號(carrier signal),使用電流/電壓雙回授,來降低D類放大器的總諧波失真。在0.35μm-CMOS製程模擬下,可得0.018%的THD,且必v效率為94.5%,晶片面積為0.38x0.48mm2。
Due to the higher power conversion efficiency, class-D amplifiers catch the attention in recent years gradually. However, because the operation is based on the switching, comparing to that of the traditional linear amplifiers, the linearity of class-D amplifier is required to improve. This paper proposed a novel dual (current/voltage) feedback, Bang-Bang Control Modulation-based Class D amplifiers circuit, with a self-tuned input structure to make sure the circuit can be expressed in terms of the Hysteresis window well. And we use the self-oscillation of the circuit structure without the need for additional external carrier signal. According to the results of simulation, the total harmonic distortion (THD) is reduced dramatically, based-on the 0.35μm-CMOS process simulation, it can get 0.018% THD, and power efficiency of 94.5%. The chip area is 0.38x0.48mm2.
