Abstract
In modern transreceivers, analog base band section is very crucial which deals with channel selectivity, antialiasing and dynamic range. Nowadays OTA become a basic building block of any analog system.For better performance of RF front end a filter which is used in base band section must include many characteristics like high linearity, tunable BW, low noise etc. A second order low pass Gm-C Filter is implemented.The core of this filter is power efficient OTA. The OTA is implemented to operate at a ±1.0 V supply voltage with a power consumption of 0.42 mW. All simulations has been performed using Tanner EDA tool using CMOS technology with parameters TSMC 0.18 µm. The simulation results of this circuit show that it has a high DC gain of 76 dB and a transconductance of 360 µS.
