Today UWB (ultra-wideband) communication is gaining a great attention from consumer electronic-industry and is expected to be adopted for many WPAN (wireless personal area network) applications. UWB (Ultra- wideband) communication standard is based the form of direct sequence or OFDM (orthogonal frequency division multiplexing) for high-date-rate application like IEEE 802.15.3a . This paper demonstrates a successful implementation and experimental verification of a CMOS analog baseband chain - variable gain amplifier and low pass filter - for a UWB wireless PAN (personal area network) receiver in a 0.18 μm CMOS process. The experiments features 40 dB linear scaled output gain and a total current of 30 mA.
