A 12-bit pseudo-differential current-source resistor-string hybrid digital-to-analogue converter with low pass rc filter.

Major concern in a high speed digital to analogue converter (DAC) is the occurrence of glitches which limiting the performance of the converter. As technology moving toward higher speed and smaller sizes, eliminating glitches is very important to ensure maximum performance of a DAC. Glitches limit m...
