Abstract

This paper describes the results of an implementation of a Bluetooth radio in a 0.18-μm CMOS process. A low-IF image-reject conversion architecture is used for the receiver. The transmitter uses direct IQ-upconversion. The VCO runs at 4.8-5.0 GHz, thus facilitating the generation of 0° and 90° signals for both the receiver and transmitter. By using an inductor-less LNA and the extensive use of mismatch simulations, the smallest silicon area for a Bluetooth radio implementation so far can be reached: 5.5 mm². The transceiver consumes 30 mA in receive mode and 35 mA in transmit mode from a 2.5 to 3.0-V power supply. As the radio operates on the same die as baseband and SW, the crosstalk-on-silicon is an important issue. This crosstalk problem was taken into consideration from the start of the project. Sensitivity was measured at -82 dBm.
