SUB-SAMPLING BASED RECEIVER USING A FREQUENCY SELECTIVE NOISE CANCELLER FOR IMPROVING THE PERFORMANCE OF A NOISE CANCELLING

摘要

PURPOSE: A sub-sampling based receiver using a frequency selective noise canceller is provided to improve the performance of a digital receiver.;CONSTITUTION: An FSSD(Frequency Selective Single to Differential converter)(32) has a band pass filter function. The FSSD changes a single input signal into a differential signal in a desired signal penetration frequency band. The FSSD changes the single input signal into a common mode signal in a not-desired signal frequency band. A CMR(Common Mode Rejector)(34) is operated as a load with a certain impedance about the differential signal which is outputted from the FSSD. The CMR functions as a filter for all common mode signals.;COPYRIGHT KIPO 2011
