PHASE IMBALANCE CALIBRATION |
| 摘要 |
A circuit for performing a residual side band calibration is described. The circuit generally includes a phase imbalance detection circuit. The phase imbalance detection circuit may include a limiter. The phase imbalance detection circuit may be independent of gain imbalance. The circuit may also include a phase imbalance correction circuit. The phase imbalance detection circuit may control coupling between an inphase path and a quadrature path. |
