Patent number: 8138808Abstract: A circuit for detecting a phase imbalance of signals includes a conversion block and a comparator coupled to the conversion block. The conversion block generates generating a direct current (DC) signal based on a first signal and a second signal. The level of the DC signal is determined by a phase difference between the first signal and the second signal. The comparator compares the DC signal to a reference signal and generates an alert signal if a difference between the DC signal and the reference signal is greater than a predetermined threshold.Type: GrantFiled: January 20, 2010Date of Patent: March 20, 2012Assignee: O2micro, IncInventors: Yongbin Yuan, Jundong Zhu, Jingwei Zhang
