Global Shunt Voltage References Market: Introduction
Shunt voltage references have two terminals, GND and OUT, and are based on a concept that is similar to zener diodes. Shunt voltage references require an external resistor module and they operate in parallel connection with the load. A shunt voltage reference may be considered as a current source that is controlled by the potential difference between the GND terminal and the OUT terminal. Regulations can be achieved by adjusting the level of current so that the difference between the supply voltage and the first resistance drop is equal to the reference voltage at the OUT gate. In other words, a constant voltage value is maintained by the shunt reference at the OUT gate by ensuring that the load current and reference current summation comes out to be a constant. These electronic modules levy no limit on the maximum power supply voltage, given that the first resistance is appropriately sized for power dissipation. The power supply connected to the shunt voltage reference circuit delivers the same quantity of maximum current regardless of the load. The supplied current flows through the reference and load, thus dropping the voltage across the first resistance to maintain the reference voltage at the OUT terminal of a shunt voltage reference module.
