This thesis project examines the design of a monolithic audio-band digital-to-analog (D/A) converter with the objective of achieving a high signal-to-noise ratio, low analog die area consumption, and low static power dissipation. Issues relating to system design, digital signal processing, sigma-delta modulation, D/A topology selection, and switched-capacitor filter design are covered. The Dire...

Solid tantalum capacitors are polarized devices designed to operate only under forward voltage bias conditions. Application of reverse voltage may produce high leakage currents with potentially destructive results. Such misapplications of these devices sometimes occur during bench testing, troubleshooting of engineering modules and/or during some malfunctions in operating systems. However, more...

The series capacitor compensation is one of the key technologies in the EHV and UHV long distance power transmission lines. This paper analyzes the operation characteristics of the main protection combined with the engineering practice when the transmission line overcompensation due to the series compensation system is modified and analyzes the influence of the transition resistance and the sys...

The design of high gain, wide dynamic range op-amps for switched-capacitor circuits has become increasingly challenging with the migration of designs to scaled CMOS technologies. The reduced power supply voltages and the low intrinsic device gain in scaled technologies offset some of the benefits of the reduced device parasitics. An alternative comparator-based switched-capacitor circuit (CBSC)...
