ABSTRACT:
A direct charge transfer digital to analog converter comprising a single reference voltage linked through a switching structure to a charge accumulation device. An accumulated charge of the charge accumulation system represents the analog output voltage. Use of the single reference voltage in conjunction with the switching structure and charge accumulation system allows for a digital signal to be converted to an analog signal with lower power consumption. Use of a single reference voltage consumes less power and space thereby making it superior to prior art digital to analog conversion systems.
