Self-calibrating high speed D/A converter |
摘要 |
A self-calibrating high speed D/A converter is provided with a calibration circuit for providing a fixed calibration current and a fixed calibration voltage during calibration mode, and a biasing circuit for biasing the calibration circuit with a first reference voltage and biasing the MSB and LSB array cells with a second reference voltage. By keeping the biasing voltage constant at the array cells during both calibrating and operating modes, such as 12 bits, the D/A converter effectively operates at high resolution, and at high operating speed.
