【 摘 要 】

References(5)We present evaluation results for DC offset in the direct conversion receiver for W-CDMA with low current consumption. Measured results indicate that steady-state DC offset is suppressed to less than 30mV and transitional variation in DC offset with gain change is limited to around 100mV. The computer simulation revealed that negligible degradation in bit error rate (BER) performance due to the DC offset transition occurs with the proposed receiver.
