Signal generator and associated phase shift apparatus and method
2013 (English)Patent (Other (popular science, discussion, etc.))
It is presented a signal generator for providing a first signal on a first output and a second signal on a second output wherein the first signal and the second signal are provided with phase shift relative to each other. The signal generator comprises: a control loop controller; a comparator; a phase shifter, the phase shifter being arranged to provide the first signal on the first output and the second signal on the second output; and a phase error detector, the inputs of which are connected to the outputs of the phase shifter and the output of which is connected to an input of the control loop controller. The output of the control loop controller is connected in a feedback loop to a first input of the comparator, and a second input of the comparator is arranged to be connected to an alternating current source.
