An IF-sampling technique rejects even-order alias channels. A 0.25 μm CMOS test chip demonstrates 27 dB anti-aliasing rejection, 70 dB dynamic range, and -121 dBm/Hz noise floor, for a 377 MHz IF GSM signal, with 52 MHz sampling rate.

Abstract
An IF-sampling technique rejects even-order alias channels. A 0.25 μm CMOS test chip demonstrates 27 dB anti-aliasing rejection, 70 dB dynamic range, and -121 dBm/Hz noise floor, for a 377 MHz IF GSM signal, with 52 MHz sampling rate.File in questo prodotto:
