Abstract :
In this paper, stability improved higher order deltasigma modulator (DSM) with an additional noise transfer function (NTF) for stability compensation is proposed. The 7th order single-loop 1-bit DSM was designed and it achieves signal-to-noise ratio (SNR) of 119 dB over 44.1kHz and 0.9 of maximum input level.
