LVDS Receiver with Active inductor load

[gilbertomaldito]

Hi,

Have anybody tried to use an active inductor to extend the bandwidth of an LVDS receiver? I read in a conference paper that the Q factor of the active inductor is not a primary concern. I just want to ask why? and what exactly is the effect of the Q factor to the preformance of the receiver?

Thank you

Andrew

Q factor will dictate the "peakiness" of the receiver. If you had a clock coming in, peakiness is useful since you jsut have 1 frequency. In case of data, probably peakiness not that critical. You are just trying to extend the BW of the circuit.

Hi love_analog, does that mean the higher the Q factor, the higher the peakness of the frequency response?

yes that is correct.
