A 1V Low-Power Single-Chip CMOS WLAN IEEE 802.11a Transceiver

A 1V WLAN IEEE 802.11a CMOS transceiver integrates all building blocks on a single chip including a transformer-feedback VCO and a stacked divider for the synthesizer and 8-bit IQ ADCs and 8-bit IQ DACs. Fabricated in a 0.18-μm CMOS process and operated at a single 1-V supply, the receiver and the transmitter consume 85.7mW and 53.2mW, including the frequency synthesizer, respectively. The total chip area with pads is 12.5 mm2.
