A 600V GaN Active Gate Driver with Dynamic Feedback Delay Compensation Technique Achieving 22.5% Turn-On Energy Saving are shown in Fig. 33.2.3. The detection branch current Isen is copied to the AMPD proportionally through current mirror pairs of MP5 and MP6. For large dv/dt value, the gate voltage of MP0 is higher, realizing lower gate overdrive voltage. Otherwise the gate overdrive voltage will increase to enable a larger driving current.
