A Gain Step Companding (COMpressing ExPANDING) Analog-to-Digital Converter
Abstract
A novel scheme for analog-to-digital conversion is described. This scheme provides a dynamic range in excess of 120 dB yet requires an output of only 9 bits. These 9 bits are utilized to transmit a companded digital word format including sign information. Use of this companded output format results in significant transmit bandwidth reduction compared with transmit bandwidths required for conventional linear bit formats. This companding results in a worst case error of 3.125%. (Author)
