초록
This work describes a power and area efficient switched-capacitor cyclic DAC for mobile display drivers. The proposed DAC can be simply implemented with one opamp two capacitors and several switches. Furthermore, the op-amp input referred offset is attenuated at the DAC output without additional offset cancellation circuitry. The operation of the cyclic DAC is verified through circuit level simulations.
