Abstract :
The main fundamental limitation of the dynamic performance of digital-to-analogue converters is their dynamic output impedances. Detailed analysis of the output impedance is provided in this Letter. A new formula is proposed to reveal that the change of output impedance during the input codes switching is the real limitation factor. To reduce this output impedance variation, two possible solutions are suggested and analysed.
