Abstract

A fully integrated Bluetooth radio transceiver has been implemented in a 0.25 μm CMOS process. A sliding-IF architecture with two-step conversion approach is used for both the receiver and transmitter. The receiver exhibits superior image-rejection performance than the low-IF receiver with out-of-band images, and suffers less DC-offset problems than the zero-IF receiver with a two-step down-conversion. The transmitter is free from the LO pulling problem. The IC achieves a sensitivity of -83 dBm and an output power of 0 dBm, both measured at the antenna port.
