Title: A RECONFIGURABLE VOLTAGE CONTROLLED CURRENT-VOLTAGE SOURCE DEVICE AND DIGITAL-TO-ANALOGUE CONVERTER COMPRISING IT
Abstract:
The present invention is enclosed in the area of voltage / voltage and voltage / current conversion, in particular with reconfigurable properties, and more specifically applied to digital-to-analogue conversion. It is an object of the present invention a reconfigurable voltage controlled current-voltage source device comprising two signal inputs, a single signal output, five resistors, four switches, a differential amplifier and two secondary amplifiers, such elements being connected in a way that provides an ability to reconfigure the output as a controlled current source or as a controlled voltage source by means of the right combination of the four switches states. Therefore, it enables the usage of a single circuitry, providing a single output. It is also an object of the present invention a digital-to-analogue converter which comprises said device and an apparatus, such as a controller, namely comprising a microcontroller or a microprocessor, comprising such digital-to-analogue converter.
