CMOS LAYOUT DESIGN FOR OTA-C BIQUAD FILTER.

This paper presents concept of universal bi-quad filter using operational trans-conductance amplifier (OTA).This OTA is biased using current of 62μA with supply voltage ?2v. TANNER environment with UMC 0.18μm technology file is used for simulation and design of this filter. This paper presents layout of an electronically tunable voltage mode universal bi-quadratic filter with three input and single output using two single ended OTA and two capacitors. The proposed filter provides low-pass, High-pass and Band-pass response by appropriately connecting the input terminals. The result of the 2nd order active bi-quad filter schematic is then compared with the layout drawn on Tanner EDA tool.
