This paper presents a low-pass filter (LPF) for an ultra-high frequency (UHF) radio frequency identification (RFID) reader transmitter in standard SMIC 0.18 mu m CMOS technology. The active-RC topology and Butterworth approximation function are employed mainly for high linearity and high flatness ...
The proposed SF stage, is used for design of a linear biquad which is then utilized in a fourth-order Butterworth low-pass filter. The simulation results of the filter for bandwidth of 10 MHz show that the IIP3 of the filter is equal to 8.22dBm, in-band noise density is 100nV/u221a...
Butterworth low-pass filtertunablecellular vehicle-to-everythingA gain and bandwidth tunable active-RC multiple-feedback (MFB) fourth-order low-pass filter is presented, which exhibits four different bandwidths of 10, 20, 30 and 40MHz and four different gain settings of 0, 4, 8 and 12dB ...
