This work presents two current-mode integrated circuits designed for sensor signal preprocessing in embedded systems. The proposed circuits have been designed to provide good signal transfer and fulfill their function, while minimizing the load effects due to building complex conditioning architectures. The processing architecture based on the proposed(More)
A physical-based model for MOS capacitors in accumulation is presented, which is able to predict the non-linear distortion accurately. The key idea of this work is to include the polysilicon gate depletion effect in that model. Several test structures based on MOS capacitors in accumulation have been implemented with the aim of validating the model and to(More)
