A 0.25/spl mu/m CMOS zero-IF transceiver with VCO and PLL (-111dBc/Hz at 1 MHz) has been implemented. The 3.1/spl times/3.1 mm/sup 2/ IC draws 86mA (RX) and 73mA (TX) from a 2.5V supply. The receiver exhibits a 5dB noise figure and 5/spl mu/s AGC settling time. RX channel filter, TX pulse shaping filter, filter calibration circuitry, 6b ADC, bandgap reference and TX preamplifier are included and controlled by a digital interface.
