Abstract
A pulse density modulator encodes an electrical parameter of an external element into a data stream signal. The electrical parameter has a property which causes a predetermined error in the data stream signal. The pulse density modulator includes a digital to analog converter having a sensor element connectable to the external element, and an adjuster circuit adapted to adjust an output of the digital to analog converter based on the data stream signal to correct the predetermined error in the data stream signal. A corresponding method of correcting a data stream signal of a pulse density modulator is also presented.
