Digital filters are used for computation, band selection, signal preconditioning, signal analysis and estimation, etc. Hardware with high efficiency are required to cope up with the rapid growth in digital signal processing applications. Digital filters are classified into two types namely, Finite Impulse Response (FIR) and Infinite Impulse Response (IIR). Due to the linear phase response and inherent stability, FIR filters are more commonly used than IIR filters. The digital filter primarily separates the unwanted signal from the wanted signal. Hybrid adder is the combination of two adders or having a logic style design in the existing adder. The multiplier using the Booth algorithm is a well-known technique for high-speed and low-cost multipliers. The hybrid adder and booth multiplier has improved performance when compared with other adders and multipliers. In this paper, a novel FIR filter is designed using GDI technique-based hybrid adder and booth multiplier. The 8-bit and 16-bit FIR filter s are designed using the proposed GDI technique-based hybrid adder and booth multiplier which saves 22.83% of power and 31.07% of delay. The proficient FIR filter using GDI technique has favorable circumstances over the conventional FIR filter. Simulation is done using Tanner EDA tool in 180nm technology and the results obtained shows a significant improvement in power consumption and delay.
