Digital-to-analog converter

An electronic system comprising:

• a digital-to-analog converter comprising:
• an input configured to receive a digital code for controlling an output voltage of the digital-to-analog converter;
• for each bit of the digital code, a voltage control circuit configured to receive the bit and to partly determine a value of the output voltage based on a value of the bit;
• and
• for each bit of the digital code, a transmission path configured to receive the bit and transmit the bit to a corresponding voltage control circuit;
• wherein each transmission path comprises a transmit circuit configured to control a time of transmission of a respective bit via the path;
• and
• wherein the transmit circuits are configured so that, for at least one change in the digital code from a first code controlling a first value of the output voltage to a second code controlling a second value of the output voltage, the voltage control circuits receive, between the first code and the second code, a third code causing a voltage pulse of desired polarity on the output voltage;
• and
• a comparator having one input configured to receive a reference voltage, and another input configured to receive the output voltage of the digital-to-analog converter.
