Low-voltage CMOS voltage squarer
2009 16th IEEE International Conference on Electronics, Circuits and Systems - (ICECS 2009), 2009A voltage squarer based on bulk-driven PMOS transistors is proposed in this paper. Circuit topology employs a voltage attenuator and the quadratic I D /V G characteristic of a MOS in saturation. The squarer was designed with a 0.8V supply voltage using standard 0.35um CMOS process, which offers large value of threshold voltage.

Integrated multivalue voltage-to-voltage converter
ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003A charge pump circuit has been developed. It can give high voltage pulses for on-chip programming EEPROM. The charge pump circuit uses a symmetrical structure and is designed to offer two possible output voltages, power supply or alternatively triple power supply, which is needed for the memory cells we use.

Review of Scientific Instruments, 1948
Integration, with respect to time, of a varying voltage is accomplished by counting the revolutions of the output shaft of a rate servomechanism. Accuracy of the order of ±0.1 percent over a 100-fold range of input voltage is obtained, with speed of response ample for many purposes.

Most of the treatment in the text so far covered the special case of the transfer function which happened to be the impedance one. In that case, input is current and output is voltage. While that is one of the most relevant cases in circuit theory, it by no means is the only one!

Automatic voltage regulator using an AC voltage-voltage converter
IEEE Transactions on Industry Applications, 2000Voltage sags and extended undervoltages are one of the main concerns of industry today. These voltage sags could cause high negative impact on productivity, which is certainly an undesirable aspect in industrial and commercial applications. Current tap-changing transformers used in distribution systems have proven to be inadequate in solving these ...

A voltage-to-voltage transducer for distorted signals in high-voltage systems
IMTC/99. Proceedings of the 16th IEEE Instrumentation and Measurement Technology Conference (Cat. No.99CH36309), 2003Measuring voltages in HV electric power systems requires scaling the signal amplitude to the levels suitable for the input section of the employed instruments and, for safety reason, insulating the measuring instrument from the system. Both these operations are usually performed by capacitive voltage transformers, but such systems do not assure high ...

Mitigation of Voltage Sag And Voltage Swell By Dynamic Voltage Restorer
2019 International Conference on Intelligent Computing and Control Systems (ICCS), 2019This work deals with reducing major voltage flickering problems by using dynamic voltage restoration and SPWM technique it helps to improve the power quality of the system. Even though voltage swag and swell occurs in transmission as well as distribution side but the problem is resolved only at the distribution side.

CMOS voltage reference based on threshold voltage and thermal voltage
Analog Integrated Circuits and Signal Processing, 2009A fully CMOS based voltage reference circuit is presented in this paper. The voltage reference circuit uses the difference between gate-to-source voltages of two MOSFETs operating in the weak-inversion region to generate the voltage with positive temperature coefficient. The reference voltage can be obtained by combining this voltage difference and the

Voltage source based voltage-to-time converter
2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS), 2015Voltage-to-time converter (VTC) circuits are used as the core component of single-slope analog to digital converters (ADCs). These VTC circuits have traditionally depended on the use of a constant current source as part of their implementation in order to have good linearity.
