Shaping inter-symbol-interference in sigma delta converter
A signal converting system is described that has a multi-segment digital to analog converter coupled to one or more error shaping loops. Each error shaping loop includes a quantizer with a feedback loop configured to generate a control signal responsive to a stream of symbols and to an error signal....

| Zusammenfassung: | A signal converting system is described that has a multi-segment digital to analog converter coupled to one or more error shaping loops. Each error shaping loop includes a quantizer with a feedback loop configured to generate a control signal responsive to a stream of symbols and to an error signal. Each error shaping loop also includes an inter-symbol-interference (ISI) shaping loop coupled to receive the control signal and to produce an ISI portion of the error signal that is responsive to inter-symbol transition rate. |
