The design, analysis, and system simulation of an adaptive processor based on a current-mode mixed analog-digital circuit is presented. The processor consists of a mixed four-quadrant multiplier and a current conveyor that performs the nonlinearity. Schematics, circuit parameters, and a high-level model are shown. The results achieved when applying this(More)
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)
In this paper a new auto-tuning digital technique is reported for continuous-time filters over VHF applications, based on phase detector. By using a 0.35 μm digital CMOS process, changes in frequency response of a 3thr-order low pass filter can be tuned with a 3.1% error over the designed value. This technique confirms the feasibility of the proposed scheme(More)
