Abstract

A low-energy 2.4GHz RF transceiver supporting 1Mb/s Gaussian Frequency-Shift Keying modulation and designed to run on a 1.5V battery is implemented in a standard 0.18μm CMOS technology. The integrated DC-DC converter can provide up to 100mA to an external load besides the current required by the transceiver. The transmitter current at 0dBm nominal output power is 11.9mA. The receiver draws 11.4mA and presents a sensitivity of -82.5dBm at a bit-error rate of 0.1% with the on-chip DC-DC converter delivering a total of 120mA. The transceiver is able to operate at a supply voltage as low as 0.8V.
