Abstract :
A new technique to implement digital interpolation filter is presented in this paper. The technique employs a sample calculation functional block which reduces the hardware required to realize the filter by orders of magnitude. The filter is realized with 80times160 mum2 using 65 nm CMOS technology. Over Sampling Rate of up to 256 is achieved for 16-bit digital data sampled at 705,600 bps. The filter dissipates 77.68 mW when operating at frequency of 833.3 MHz.
