Abstract
This paper describes a sharp-rejection technique in designing active-RC LPF for MB-OFDM UWB applications. Sharp rejection is attributed to the combination of different AC characteristic of three Biquads in series. A simple operational amplifier (Op-amp) is adopted to ensure high frequency and high linear performance for the designed filter. The cutoff frequency is 264MHz, with 13dB rejection at 290MHz and about 50dB at twice bandwith. the LPF is designed in 0.13um IBM CMOS process with pass-band ripple of less that 1dB, IIP3 is 23dBm while cnsuming 8.4mA from 1.5V supply.
