Abstract
Delta-Sigma noise-shaping coder with two analog integrators and Delta-Sigma decoder with two digital integrators. The coder comprises an operational amplifier with two analog integrators in its feedback loop and two cascaded flipflops both connected to the input of the operational amplifier through resistors having a predetermined ratio. The configuration of the integrators is particular and results of the identification of the z-transfer function of the coder to be designed with the p-transfer function of a known integrator (p, Laplace's variable). The decoder comprises a digital integrator-filter of order two and two cascaded flipflops both connected to the input of the filter through amplifiers having gains in a predetermined ratio.
