The Trade-Off between Surge-Current Capability and Reverse- Recovery Behaviour of High-Voltage Power Diodes

This paper discusses the trade-off between surge-current capability on the one hand and reverse-recovery charge, ruggedness and softness of high-voltage diodes on the other hand. Diodes with a CIBH (Controlled Injection of Backside Holes) structure in front of the cathode and a highly doped p-region combine high surge-current capability with reverse-recovery ruggedness and softness. This can be...

Breakdown Voltage of High-voltage GaN FETs

GaN FETs offer superior advantages in high-voltage and high-temperature operation due to its large bandgap (3.4 eV) and high breakdown field strength (3.3 MV/cm). This combination of the large bandgap and high breakdown field makes these devices very attractive for power switching applications. In this regard, a key figure of merit is the breakdown voltage of the transistor, which must be high ...

An Ultra High CMRR Low Voltage Low Power Fully Differential Current Operational Amplifier (COA)

this paper presents a novel fully differential (FD) ultra high common mode rejection ratio (CMRR) current operational amplifier (COA) with very low input impedance. Its FD structure that attenuates common mode signals over all stages grants ultra high CMRR and power supply rejection ratio (PSRR) that makes it suitable for mixed mode and accurate applications. Its performance is verified by HSPI...

High-Speed, High-Voltage Diodes for High Resolution Monitors

In today’s multimedia orientated society, display devices used as man-to-machine interfaces to facilitate communication have become an indispensable part of daily life in both the public and industrial sectors. CRTs (cathode ray tubes) are the most widely used electric display devices because they provide a low cost, large screen, full-color image with high resolution, high brightness, and quic...
