Abstract
A receiver includes: an automatic gain controller (AGC) configured to receive an analog signal; an analog-to-digital converter (ADC) configured to receive an output from the AGC and to output a digitized signal, wherein a most significant bit of the digitized signal corresponds to a sliced data, and a least significant bit of the digitized signal corresponds to an error signal; and an adaptation unit configured to control the AGC, the ADC, or both the AGC and the ADC, based at least in part on the digitized signal to achieve a desired data digitization and data slicing.

A receiver, comprising:
- an automatic gain controller (AGC) configured to receive an analog signal;
- an analog-to-digital converter (ADC) configured to receive an output from the AGC and to output a digitized signal, wherein a most significant bit of the digitized signal corresponds to a sliced data, and a least significant bit of the digitized signal corresponds to an error signal;
- and
- an adaptation unit configured to control the AGC and a reference voltage of the ADC, based at least in part on the digitized signal to achieve a desired data digitization and data slicing.
- an adaptation unit configured to control the AGC, the ADC, or both the AGC and the ADC, based at least in part on the digitized signal to achieve a desired data digitization and data slicing.
A receiver, comprising:
- an automatic gain controller (AGC) configured to receive an analog signal;
- an analog-to-digital converter (ADC) configured to receive an output from the AGC and to output a digitized signal, wherein a most significant bit of the digitized signal corresponds to a sliced data, and a least significant bit of the digitized signal corresponds to an error signal;
- an adaptation unit configured to control the AGC, the ADC, or both the AGC and the ADC, based at least in part on the digitized signal to achieve a desired data digitization and data slicing;
- and
- a digital signal processor (DSP) coupled to the ADC, wherein the DSP is configured to be switched on when the receiver is performing processing for long reach application, and is configured to be switched off when the receiver is performing processing for short reach application.
A method performed by a receiver, comprising:
- providing an output by an automatic gain controller (AGC) based on an analog signal;
- providing a digitized signal by an analog-to-digital converter (ADC) based on the output from the AGC, wherein a most significant bit of the digitized signal corresponds to a sliced data and a least significant bit of the digitized signal corresponds to an error signal;
- and
- controlling the AGC and a reference voltage of the ADC, based at least in part on the digitized signal to achieve a desired data digitization and data slicing, wherein the act of controlling is performed by an adaptation unit.
