Abstract
A digital to analog converter (DAC) circuit includes pulse generator circuit for generating voltage pulses having a predetermined length and shape. The voltage pulses are used to control the generation of current pulses generated by a voltage to current converter. The voltage to current converter includes a set of switchable resistors where the resistance value provided by the set is dependent upon a digital value of a digital signal. In some embodiments, the current amplitude of the current pulses is dependent upon the resistance value and is indicative of the digital value.
