Abstract
Differential architectures for both first order error diffusion and first order sigma–delta modulators are presented in this paper. Techniques required to transform single-ended architectures to differential architectures are discussed which are suitable for implementation in both p–i–n and n–i–n SEED technologies. Descriptions of common SEED circuit modules, together with SPICE behavioural simulations are also presented. A feature of the architectures presented is that they can be fully integrated into a single substrate using MEMS technology. This can be done by incorporating integrated optical waveguides together with MMIC technology. The goal of this work is a fully integrated differential optical oversampling modulator with extremely high resolution and linearity.
