Abstract: This thesis presents the design of a low-power 2.4-GHz BPSK/OOK transceiver for wireless sensor network applications. The transceiver is optimized for asymmetrical sensor-gateway communications where different modulation schemes and data-rates are used in the uplink and downlink paths. The transceiver is reconfigurable to support both the sensor and gateway modes. A new design of fully integrated Class-E power amplifier (PA) is presented which improves the energy efficiency of the transmitter. Implemented in 0.13 µm CMOS technology, the transceiver occupies an on-chip area of 3.3 mm<SUP>2</SUP> including bonding pads. When configured in sensor mode, the BPSK transmitter consumes only 3.6 mW at 0 dBm output power with 1 to 8 Mbps data rate, and the 0.78 mW OOK receiver achieves sensitivity of -80 dBm at 100 kbps data rate. In gateway mode, the sensitivity of the receiver is -84.5 dBm for 5 Mbps BPSK.
