  • Abstract
    An adaptation of the hard-thresholding denoising method for analogue circuits is presented. The proposed approach has been proved with a chip fabricated in 0.5 μm CMOS technology. The system works for signals contaminated with white Gaussian noise in the range 100 kHz to 1.6 MHz. On-chip measurements demonstrate a noise reduction up to 7 dB.
