CCCII (Current Controlled Second Generation Current Conveyor) based reconfigurable current-mode Analog Baseband (ABB) low pass filter is presented in this paper. The configurability of the filter is realized with the parasitic impedance at X terminal of CCCII. The 4th order filter operates high tuning range as 1.7 MHz to 17 MHz approximately. Thus, the operation range covers the wireless applications of Bluetooth, CDMA2000, Wideband CDMA, and IEEE 802.11a/b/g/n wireless LANs. Also, the proposed architecture is suitable for other wireless applications such as 3G/4G. In this respect, TSMC 0.18 mu m technology is used with Cadence environment to implement the proposed filter, whilst Monte-Carlo analysis and temperature behavior are investigated under post-layout realization of the proposed Active-C based ABB filter (100 mu mx42 mu m). In comparison with the previous studies in the literature, proposed architecture gives promising results under different operating conditions for the ABB applications.
