Adaptive Cascaded Equalization Circuits with Configurable Roll-Up Frequency Response for Spectrum Compensation
The present disclosure provides adaptive cascaded equalization circuits for frequency spectrum compensation. The cascaded equalization are formed in circuit configurations to achieve configurable roll-up frequency responses to compensate for the loss of signal channels in the wire-line or optical communications particularly but not exclusively for the loss of signal trace in the wire-line communications and photodetectors used in the optical communications. These cascaded equalization circuits include two or more stages of equalizers. The peaking frequencies of each stage are set to be different from each other so that the overall frequency response characteristic has a unique frequency response with a roll-up slope. The equalization function is automatically tuned by an adaptive feedback control loop.
