Sensor device and a method of current modulation switching using a two-wire current interface

A sensor device comprising:

• a two-pin current interface including an input pin configured to draw an input current into the sensor device and an output pin configured to output an output current from the sensor device, wherein the output current is derived from the input current;
• a sensor configured to generate a measurement signal based on a measured quantity;
• and
• a current modulator configured to generate a current signal based on the measurement signal, wherein the current signal comprises at least two main current states defining a current pulse, and wherein the output current toggles between the at least two main current states based on the measurement signal,
• wherein the current modulator is further configured to modulate the output current such that the output current is increased to a first current level greater than the at least two main current states for a first duration, wherein the output current is increased to the first current level at an initial phase of the current pulse, and
• wherein the current modulator is further configured to modulate the output current such that the output current is decreased to a second current level less than the at least two main current states for a second duration, wherein the second current level is equal to or greater than zero and the output current is decreased to the second current level at a terminal phase of the current pulse.
