钟形幅度均衡器是均衡通路幅度畸变的常用器件。开关电容电路适宜采用LSI实现,以做到体积小、成本低。本文采用一种双二阶电路作为钟形幅度均衡器的基本节,其特点是对寄生电容不灵敏。经预扭曲后的计算特性可与设计要求达到一致。这种二阶节的级联可用来满足更复杂的均衡要求。 Bell amplitude equalizer is a common device amplitude equalizer path distortion. Switching capacitor circuit suitable for LSI implementation, in order to achieve small size, low cost. In this paper, a double second-order circuit is used as the basic section of bell-shaped amplitude equalizer, which is characterized by insensitivity to parasitic capacitance. After the pre-distortion of the computing characteristics of the design requirements can be achieved. This second-order concatenation can be used to satisfy more complex equalization requirements.
