This paper presents a lossy gyrator, which is used to implement a universal second order current mode filter. The proposed lossy gyrator uses conventional Second Generation Positive Current Conveyor (CCII) as a basic building block, which has -3 dB bandwidth of 230 MHz and a total power consumption of 15.31 mu mathbf{W}. A universal second order current mode filter is designed using proposed lossy gyrator, which achieves a high cutoff frequency of 18 Hz in low pass mode, a low cutoff frequency of 345 Hz for high pass, and a band pass response with resonating frequency at 90 Hz with a total power dissipation of 57 mu mathbf{W}. Simulation is done using standard 180 nm CMOS technology at ±0.5 V supply voltage.

Abstract
This paper presents a lossy gyrator, which is used to implement a universal second order current mode filter. The proposed lossy gyrator uses conventional Second Generation Positive Current Conveyor (CCII) as a basic building block, which has -3 dB bandwidth of 230 MHz and a total power consumption of 15.31 mu mathbf{W}. A universal second order current mode filter is designed using proposed lossy gyrator, which achieves a high cutoff frequency of 18 Hz in low pass mode, a low cutoff frequency of 345 Hz for high pass, and a band pass response with resonating frequency at 90 Hz with a total power dissipation of 57 mu mathbf{W}.
