Hi guys,
i'm working on a 10bit charge redistribution switched-capacitor serial DAC. The converter works with V_ref=10mV=V_fs. In this way, the converter starts convertingthe input from 0 to 10mV. The problem is that i need this very small LSB=9.8uV but at the end of the conversion, the output must have 300mV DC voltage (lets say a 10mVpp sinusoidal signal with 300mV DC). The DAC output goes to an high gain voltage buffer stage in order to drive a capacitive load. How can i introduce the DC voltage? Level-shift after the buffer or internally within the dac?
Thank you in advance! :)
