Voltage Differencing Inverting Buffered Amplifier (VDIBA) is a versatile Analog building block, gaining much attention in Analog signal processing applications. Inclusion of two input bulk-driven (BD) MOS transistor in VDIBA structures introduces functionality, tunability, and power reduction. This paper discusses the design, implementation, and potential applications of Two input bulk-driven (BD) MOS transistor VDIBA, highlighting the advantages of such an approach over traditional CMOS-based implementations. The proposed circuit has been simulated using on Pspice using 180nm technology parameters. The simulation results show that the circuit has input signal range of ± 0.60 V, Transconductance of 45 μS and very small quiescent power dissipation of 0.086 mW. Also, the process corner analysis has been done to check the robustness of the circuit against process variations
