Abstract:
This paper proposes an approach for designing a
R-2R 10 bit Digital to Analog Converter (DAC) which could
be made to operate at low voltage supply by efficiently
exploiting the cascaded Operational Amplifier (Op-Amp)
architecture. The DAC operates at a 3V power supply with
a settling time of 50-100ns , dynamic range of around 50-60
dB for signals upto a frequency of 10Mhz. Graph &
simulation results are provided to verify the stability of the
Op-Amp used in DAC
