Voltage-mode threshold-independent analogue multiplier

International Journal of Electronics, 2009
In this article, a new threshold-independent four-quadrant analogue multiplier is designed and developed. It is based on the square-law of the MOS transistor in the saturation region and quarter-square algebraic identity. The circuit structure uses voltage summing and voltage-mode squaring stages.

Low-power CMOS voltage-Mode quaternary latched comparator

2015 23rd Iranian Conference on Electrical Engineering, 2015
In this paper, a low-power CMOS voltage-mode quaternary latched comparator is presented. The proposed circuit operates in two modes. In comparison mode, it compares the input analog signal with three predefined threshold levels and returns a quaternary digit at the output accordingly, and in latch mode, it saves the output voltage which was generated ...

Cascadable Voltage-Mode Multifunction Biquad Employing Single OTRA

Frequenz, 2007
A voltage-mode (VM), multi-input single-output (MISO) type multifunction biquad is proposed. It uses only one operational transresistance amplifier (OTRA) as the active element, while previously reported VM multifunction filters require more OTRAs.

Voltage-mode MISO OTA-C biquad filter

2011 IEEE Symposium on Industrial Electronics and Applications, 2011
This paper presents a new voltage-mode multifunction biquad filter with three-input single-output using simple operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed circuit can simultaneously realize voltage-mode lowpass, bandpass, highpass, bandstop and allpass filter responses at a high impedance input terminal.

Voltage-mode biquadratic filters using single DDCCTA

AEU - International Journal of Electronics and Communications, 2016
Abstract This paper presents two voltage-mode universal biquadratic filters based on a single differential difference current conveyor transconductance amplifier (DDCCTA). Each of the proposed circuits comprises a single DDCCTA combined with passive components that can realize lowpass (LP), highpass (HP), bandpass (BP), bandstop (BS), and allpass (AP)

A low power duobinary voltage mode transmitter

2017 IEEE/ACM International Symposium on Low Power Electronics and Design (ISLPED), 2017
This paper presents a novel low power duobinary voltage mode transmitter in 90-nm CMOS process for wireline communication. As a matter of fact, voltage mode transmitters potentially save much more power than current mode transmitters. By adding a medium level, a half supply voltage, to conventional NRZ voltage mode transmitters, duobinary coding can ...
