技術摘要 / Our Technology: |
一種校正增益錯誤的自校正系統及其自校正方法,透過電性連接校正電容於乘法式數位類比轉換器中的運算放大器作為正回授路徑,以便在低增益的情況下調整校正電容來改變級間增益及校正增益錯誤,用以達成降低運算放大器所造成的增益錯誤之技術功效。
A self-calibration system for calibrating gain error and self-calibration method thereof is disclosed. With connecting a calibration capacitor as a positive feedback path for an operational amplifier (op-amp) in multiply digital to analog converter (MDAC), it changes the inter-stage gain and calibrates gain error by adjusting the calibration capacitor. The mechanism is used to reduce the gain error caused by the op-amp.
