Abstract
Devices and methods for digital to analog conversion (DAC) are provided, in which the analog outputs of an even number of digital to analog converters are combined. The individual converters operate on the same data but there is a relative time delay between the input digital signal received by one or more of the converters and the input digital signal received by other of the converters, wherein the delay is a fraction of the data sample period. Moreover, the data signal fed to half of the converters has an inverse relationship with the data signal fed to the other half of the converters and their analog outputs are subtracted. Dither and filtering techniques may also be employed.
