A 2.4-GHz low complexity polar transmitter using dynamic biasing for IEEE 802.15.6

A 2.4 GHz polar transmitter compliant with the IEEE 802.15.6 standard is presented in this paper. A Linearized class-C power amplifier, employing dynamic biasing is used to minimize the adjacent channel interference and satisfy the defined spectrum mask requirements. An FBAR based frequency synthesizer enables fast startup and channel switching times. It is capable of addressing all the channels within the MBAN and ISM bands (2.36-2.48 GHz). The transmitter was integrated in 65 nm CMOS technology. It provides 0 dBm of output power while drawing 8.7 mA of current from a 1.2 V supply. The standalone power amplifier exhibits peak efficiency of 16%. © 2015 IEEE.
