Low Power Consumption is the main target in today’s Technological aura and as Very large scale integrated circuit (VLSI) designing is very complex and it require much conceding nature to realise application precise objective. With increasing the efforts to reduce Power Consumption and to reduce W/L ratio, Low pass and high pass filter structure have widespread application and using CMOS Operational Trans-conductance amplifier gives capability to perform well in Nano-meter range as it has better control over short channel effect and other scaling problem like gate leakage, sub-threshold conduction. Low pass and high pass filter based on OTA for VHF and UHF frequency applications. At high frequencies, the OP AMP based active filters has limited performance. We cannot change the values of resistors and inductors but OTA-C filter provides ability to change their values by changing trans-conductance of OTA. The proposed filter consists of OTA and capacitors. This filter shows low sensitivity to passive components, low component count and ease in design. The simulations are done using Tanner EDA version 16.2 at 0.25nm technology.
