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.
