dc.description.abstract | A dual-mode transceiver integrates the transmitter
of 0-dBm output power and the receiver for both Bluetooth with 87 dBm sensitivity and 802.11b with 86 dBm sensitivity in a single chip. A direct-conversion architecture enables the maximum reuse and the optimal current consumption of the various building blocks in each mode for a low-cost and low-power solution. A single-ended power-amplifer (PA) driver transmits the nominal output power of 0 dBm with 18-dB gain control in 3-dB steps. Only little area overhead is required in the baseband active filter and programmable gain amplifier (PGA) to provide the dual-mode capability with optimized current consumption. The dc-offset cancellation scheme coupled with PGAs implements the very low high-pass cutoff frequency with a smaller area than required by a simple coupling capacitor. Fabricated in 0.25- m CMOS process, the die area is 8.4 mm2 including pads, and current consumption in RX is 50 mA for Bluetooth and 65 mA for 802.11b from a 2.7-V supply. | en |
