Abstract
The present study proposes a new dynamic two-level quantizer, called as hybrid delta modulator (Delta(H)-M), which combines the features of both delta-modulator and delta-sigma modulator. In the transient state, the Delta(H)-M exhibits the dynamical behaviour of delta modulator (Delta-M) while in steady state, its behaviour is similar to delta-sigma modulator (Delta Sigma-M). This study investigates about various dynamics of the proposed Delta(H)-M in both continuous and discrete-time domains. The stability conditions of Delta(H)-M are derived using the theory of sliding and quasi-sliding mode. The theoretical results are validated through extensive simulations.
