A low-power architecture for a phase-splitting passband equalizer (PSPE) is proposed 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. Index Terms - ATM-LAN, CAP, Hilbert transform, low-power.
