<p>In this paper, a designed circuit used for low-frequency filters is implemented and realized the filter is based on frequency-dependent negative resistance (FDNR) as an inductor simulator to substitute the traditional inductance, which is heavy and high cost due to the coil material manufacturing and size area. The simulator is based on an active operation amplifier or operation transconductance amplifier (OTA) that is easy to build in an integrated circuit with a minimum number of components. The third and higher-order Butterworth filter is simulated at low frequency for low pass filter to use in medical instruments and low-frequency applications. The designed circuit is compared with the traditional proportional integral controller enhanced (PIE) and T section ordinary filter. The results with magnitude and phase response were compared and an acceptable result is obtained. The filter can be used for general applications such as medical and other low-frequency filters needed.</p>

Prediction of millimeter(mm)-wave radio signals can be beneficial in recreating and repeating atmospheric conditions in a controlled, laboratory environment. A path-loss model has been proposed that accounts for free-space losses, oxygen absorption, reflection and diffraction losses, and rain-rate attenuation at mm-wave frequencies. Two variable passive low-pass-integrated circuit filter structures for attenuation in the 57–64 GHz unlicensed frequency band have been proposed, designed, simulated, prototyped in a 130-nm SiGe bipolar complementary metal-oxide semiconductor process, and measured. The filters are based on the Butterworth and Chebyshev low-pass filter topologies and investigate the possibility of using the structures to perform amplitude attenuation of mm-wave frequencies over a short distance. Both filters are designed and matched for direct coupling with equivalent circuit models of dipole antennas operating in this frequency band. Full integration therefore allows prediction of atmospheric losses on an analog, real-time, basis without the requirement of down-converting (sampling) to analyze high-frequency signals through a digital architecture. On-wafer probe measurements were performed to limit parasitic interference from bonding wires and enclosed packaging.
