Abstract: This work proposes the design and simulation of a novel Chebyshev low pass filter. This proposed design incorporate the use of floating inductor, resistor and also the grounded resistor with the help of CMOS based operational transconductance amplifier (OTAs). The value of proposed floating inductor can be modified by adjusting the bias current input. The filters are synthesized from 3rd to 5th order low pass LC prototype and designed using ladder structure. All the simulations are done on Verilog AMS. The results of simulation show that the novel structure design exhibit better cut off frequency, tuning range, less ripples as compared with the conventional design. The overall performance of the filter is improved by using floating inductor.
