    摘要： Front-end circuitry for a data receiver and related systems, methods, and devices are disclosed. The front-end circuitry includes a passive equalizer, which includes a signal input, an equalizer output including a first equalizer output and a second equalizer output, a first signal path, and a second signal path. The first signal path is between the signal input and the first equalizer output. The first signal path has a first frequency response. The second signal path is between the signal input and the second equalizer output. The second signal path has a second frequency response. The second frequency response exhibits substantially inverse behavior to that of the first frequency response. An amplifier circuit is configured to combine a first equalizer output signal from the first equalizer output with a second equalizer output signal from the second equalizer output to obtain an equalized output signal.

    摘要： An equalizer for compensating transmission losses of electronic communication signals includes a circuit board and a compensation module. The compensation module includes a pair of input pins, a pair of output pins, first and second resistors, first and second vias, and a pair of micro-strips. When a signal transmitted by the circuit board is received by the input pins, a first part of the signal is directly outputted from the output pins, a second part of the signal is reflected by the first resistor and transmitted back to the output pins to be outputted, and a third part of the signal is reflected by the second resistor and transmitted back to the output pins to be outputted, such that the output of the equalizer applies two stages of compensation.

    摘要： An apparatus includes a capacitor coupled between a first node responsive to receive an input signal and a second node. The apparatus includes a first circuit coupled to the second node and a third node. The first circuit is selectively operable to separately configure at least one of a low-frequency gain of an equalizer and a pole of the equalizer. The equalizer includes the first circuit and the capacitor. The second node is responsive to receive an equalized version of an AC signal of the input signal in a first mode of the apparatus. The second node is responsive to receive a non-equalized version of the AC signal of the input signal in a second mode of the apparatus. The equalized version of the AC signal of the input signal may be a level-shifted and equalized version of the AC signal in the first mode of the apparatus.
