Abstract
Recently, continuous time delta-sigma modulators are widely studied, because its switch-less architecture enables wide band operation even if a power supply voltage is low. In this paper, high-order integrators are newly developed in order to reduce the number of operational amplifiers used in the integrator path of the delta-sigma modulators. The high order modulator is applicable for both multiple feedback and feed forward compensation architectures. The design example of 5^<th> order delta sigma modulator composed of 2^<nd> order integrators is detailed.
