High Voltage Tolerant Output Buffer Design for Mixed Voltage Interfaces
2005 IEEE International Symposium on Circuits and Systems, 2005This paper presents the design of a mixed voltage 3.3V/5.5V CMOS output buffer. The proposed design technique eliminates gate-oxide overstress and output to supply current flow when common bus voltage is higher than the supply voltage. While this paper discusses the 3.3V/5.5V supply combination as an example, the same circuit topology can be used for ...

Output voltages of a multiswitch inverter
IEE Proceedings B Electric Power Applications, 1980The well known 3-phase inverter incorporates three pairs of power switching devices. When the number of phases exceeds three, there is the possibility of obtaining a phase-balanced system from less switch pairs than the number of phases. With particular reference to multiphase machines, this paper examines the effect of switch-pair elimination on ...

A novel voltage doubler rectifier for high output voltage applications
The 2010 International Power Electronics Conference - ECCE ASIA -, 2010By integrating a novel voltage doubler rectifier with a classical current-fed converter, a current-fed push-pull boost converter with voltage doubler (CFBCVD) is presented. In addition to having a non-pulsating input current, recovery of the secondary leakage energy, low output capacitor current ripple, much lower rectifier diode voltage stress, and ...

Frequency-output fiber-optic voltage sensor for high-voltage lines
IEEE Photonics Technology Letters, 2001We report a frequency-output fiber-optic voltage sensor for high-voltage lines. The sensor is based on the linear piezoelectric effect of a PZT ceramic tube. A length of single-mode fiber was wound onto the tube and was inserted in one arm of a Mach-Zehnder interferometer. When an ac voltage is applied to the piezoelectric, the interferometer generates

Single-output reconfigurable voltage controlled voltage-current source
2017Atualmente, a operação de conversão de sinais digitais para analógicos é bastante utilizada. Este tipo de conversão, efetuada por conversores digitais-analógicos (DACs), pode ser encontrado em inúmeros circuitos integrados (ICs) comerciais. Hoje em dia, um DAC pode ter saída só em tensão, só em corrente ou em tensão e corrente, mas disponibilizadas em ...

Prediction of the output voltage of DC voltage standards
2009In this paper we report some methods which upgrade the measurement uncertainty evaluation in analysis of the prediction of the output voltage of DC Reference Standards (Fluke 732A at 1 V, 1, 018 V and 10 V levels). The monitoring of long-term stability of Zener-based voltage reference standards is one of the main tasks of Primary Electromagnetic ...

A low voltage low output impedance CMOS bandgap voltage reference
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013A low voltage bandgap architecture is proposed. The opamp in the proposed bandgap is used for both generating the output reference voltage (Vref) and achieving low output impedance. To allow Vref to have different values within the supply voltage limits, a transconductor is proposed and used in conjunction with the opamp to supply the biasing currents ...
