How many bits do you need – Part 2

Quantization also impacts system performance when it occurs in the filter response calculation. Quantization occurs in the filter response due to the physical constraints of the processing ...

Practical considerations for estimating SNR and SFDR

It is not surprising that the world around us is getting more and more digitized. One reason might be that manipulation, storage, and usage of data in digital form is more convenient and easier than ...

Pyramid Vector Quantization and Bit Level Sparsity in Weights for Efficient Neural Networks Inference

This paper discusses three basic blocks for the inference of convolutional neural networks (CNNs). Pyramid Vector Quantization [1] (PVQ) is discussed as an effective quantizer for CNNs weights ...

Using Delta-Sigma Can Be As Easy As ADC (Part 5)

My last column showed how a single-stage delta-sigma modulator (DSM) produces an output that is a sum of the low pass-filtered input signal and the high pass-filtered quantization noise (see “Part 4,” ...
