  • Method for transferring signals via transmission interface and communications apparatus utilizing the same
    Patent number: 11929767
    Abstract: A transmission interface between at least a first module and a second module is proposed. The transmission interface includes at least two physical transmission mediums. Each physical transmission medium is arranged to carry a multiplexed signal in which at least two signals are integrated. The at least two physical transmission mediums include a first physical transmission medium arranged to carry a first multiplexed signal including a first IF signal and a reference clock signal. The first IF signal and the reference clock signal are at different frequencies.

  • Drive circuit for reducing inductive kickback voltage
    Patent number: 7639064
    Abstract: In one embodiment a drive circuit includes two comparators which are adapted to sense kickback voltage generated in an inductive load and conduct two field-effect transistors connected to ground in a very short period of time so as to quickly reduce the kickback voltage to a minimum value. In another embodiment only one comparator is provided.
