This paper gives an overview of some of the effects caused by circuit mismatch and parasitics in binary weighted digital-to-analog (DAC) converters, and, as a special case, a current-steering CMOS converter. Matlab is used as a behavior-level simulator. In telecommunications applications, the frequency-domain parameters are of the greatest importance. Therefore, the characterization of the devi...

Structural Health Monitoring (SHM) is the science and technology of monitoring and assessing the condition of aerospace, civil, and mechanical infrastructures using a sensing system integrated into the structure. Impedance-based SHM measures impedance of a structure using a PZT (Lead Zirconate Titanate) patch. This chapter presents a lowpower wireless autonomous and active SHM node called Auton...

this paper presents a new component within the flexible ac-transmission system (FACTS) family, called distributed power-flow controller (DPFC). The DPFC is derived from the uni-fied power-flow controller (UPFC). The DPFC can be considered as a UPFC with an eliminated common dc link. The active power ex-change between the shunt and series converters, which is through the common dc link in the UP...

The SVC (Static Var Compensator) based on voltage source converter (VSC) is used for voltage regulation in transmission and distribution system. The SVC can rapidly supply dynamic VARs required during system faults for voltage support. The apparent impedance is influenced by the reactive power injected or absorbed by the SVC, which will result in the under reaching or over reaching of distance ...

High-frequency characteristic of a TVC-input circuit becomes dominant factor in the AC-DC transfer difference at frequencies higher than 100 kHz. In order to evaluate the high-frequency characteristics of TC modules up to 1 MHz, a High-Frequency-standard TVC (HF-TVC) has been developed at AIST, in collaboration with Nikkohm Co. Ltd. The HF-TVC is designed such that the frequency characteristic ...

A 10-bit 140MS/s digital-to-analog converter (DAC) with improved current mirror is presented. In order to improve the resolusion of a 10-bit DAC, a segmented decoding plus R-2R architecture will be introduced. DAC system modeling shows that the dynamic performance of the DAC is strongly dependent on the output impedance of DAC current source. The gain-boosting technique is applied to increase t...

In this paper a voltage controlled current conveyor is presented wherein the intrinsic transresistance is controlled by a voltage variable current source which is realized using floatinggate MOSFETs. The resultant conveyor has been used to implement an impedance converter which is further used as inductance simulator. The characteristics of the conveyor and inductance simulation have been obtai...
