发明名称 Systems and method for automatic quadrature phase imbalance compensation using a delay locked loop
摘要 An automatic quadrature phase compensation system comprises an on-chip analog phase sense circuit capable of detecting small differences in quadrature phase error and providing a corresponding DC voltage, a voltage-controlled or programmable phase delay circuit to implement quadrature phase error correction, and a feedback system or compensation engine used to process the sensed error voltage and apply a corresponding correction signal to the adjustable phase delay.
