Multiphase receiver with equalization
First Claim
1. A multiphase receiver to compensate for intersymbol interference in the sampling of an input signal, the multiphase receiver comprising:
- a first integrating receiver to integrate and sample data of the input signal on a first phase of a clock;
a second integrating receiver to integrate and sample data of the input signal on a second phase of the clock; and
an equalization circuit to adjust integration by the first integrating receiver dependent on a result of integration of data previously received by an integrating receiver distinct from the first integrating receiver, and to adjust integration by the second integrating receiver dependent on a result of integration of data previously received by an integrating receiver distinct from the second integrating receiver.

Abstract
A multiphase receiver to compensate for intersymbol interference in the sampling of an input signal includes a first integrating receiver to integrate and sample data of the input signal on a first phase of a clock and a second integrating receiver to integrate and sample data of the input signal on a second phase of the clock. The multiphase receiver also includes an equalization circuit to adjust integration by the first integrating receiver dependent on a result of integration of data previously received by an integrating receiver distinct from the first integrating receiver, and to adjust integration by the second integrating receiver dependent on a result of integration of data previously received by an integrating receiver distinct from the second integrating receiver.

22. A multiphase receiver to compensate for intersymbol interference in the sampling of an input signal, the multiphase receiver comprising:
-
first means for integrating and sampling data of the input signal on a first phase of a clock; second means for integrating and sampling data of the input signal on a second phase of the clock; and means for correcting for intersymbol interference by applying portions of respective integration voltages generated by each of the first and second means to the other of the first and second means.

23. A method of compensating for intersymbol interference in the sampling of an input signal, the method comprising:
-
integrating and sampling data of the input signal on a first phase of a clock using a first integrating receiver; integrating and sampling data of the input signal on a second phase of the clock using a second integrating receiver, wherein integration by the second integrating receiver is adjusted responsive to a result of integration of data previously received by an integrating receiver distinct from the second integrating receiver; and wherein integration by the first integrating receiver is adjusted responsive to a result of integration of data previously received by an integrating receiver distinct from the first integrating receiver. - View Dependent Claims (24)
