Abstract
A data converter includes a single-end capacitive digital to analog converter (DAC); a transconductance (GM) buffer having an output, a positive input coupled to the DAC and a negative input coupled to the output; a resistor and a capacitor load in parallel coupled to the output at one terminal and to ground at the other terminal. The developed architecture of comprising single end capacitive DAC and GM-based buffer provides fast conversion rate, low current consumption, small silicon area and wide supply range for general-purpose auxiliary DAC applications.
