Abstract :
An integrated 6.2-9.5GHz CMOS UWB receiver for WiMedia MB-OFDM is proposed. The fully differential receiver consists of a wideband LNA and a down conversion mixer with high and low gain mode. A low-pass filter and a programmable gain amplifier are also included. The chip was fabricated in TSMC 0.13-μm RF CMOS process. Measurement results show that the receiver achieves voltage gain from 21dB to 63dB with 2dB/step and NF of 3.2-4.2dB over 6.2-9.5GHz and OIP3 of 13.4dBm. Power consumption is only 47mA with 1.2-V supply voltage.
