Abstract

A low-power architecture for a phase-splitting passband equalizer (PSPE) is proposed for a transceiver in this correspondence. The Hilbert relationship between the in-phase and quadrature-phase equalizers in the PSPE is exploited to develop the proposed architecture. It is shown via analysis and simulations that in a 51.84-Mb/s ATM-LAN environment, the proposed receiver results in (1) a net saving in power if the length of the Hilbert filter is less than 130, and (2) a saving of up to 20% can be achieved with a degradation in signal-to-noise ratio of less than 0.5 dB
