Description
Summary:An RF receiver for carrier aggregation employing a low noise amplifier with a current reusing technique and a frequency-band switchable transformer is demonstrated in a 28nm LP CMOS technology. The proposed single-ended low-noise amplifier can support multiple-channel RF signals for both inter- and intra-band carrier aggregation with high performance and low DC current consumption. Moreover, a frequency-band switchable transformer is developed to realize a size-efficient receiver for handling three carrier components carrier aggregation. The receiver operates at frequency bands, ranging from 0.7 to 2.7 GHz. The receiver has conversion gain more than 70 dB and noise figure of less than 3.5 dB for all carrier aggregation combinations.
