380 MHz Low-Power Sharp-Rejection Active-RC LPF for IEEE 802.15.4a UWB WPAN.
In: 2009 IEEE Symposium On Circuits and Systems, 24th-27th May 2009, Taipei, Taiwan.
This paper describes a wide-band sharp-rejection
active-RC low pass filter (LPF) for pulse-based UWB IEEE
802.15.4a WPA, 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 performance for the designed filter. The LPF is designed in 0.13μm TSMC CMOS process. The cutoff frequency is 380MHz with about 50% of the tuning range from 300-500MHz. The rejection is 40 dB at 600 MHz. The passband ripple is less than 1.5dB and the filter consumes 4.6mA from 1.2V supply. Core chip size is 580 x 700μm2.
