Abstract: Embodiments provide a device that includes a first circuit having a first input to receive a first sine wave signal and a second input to receive a second sine wave signal in quadrature with respect to each other and a current mode logic gate having a first input coupled to a first output of the first circuit and a second input coupled to a second output of the first circuit. The first circuit configured to deliver a first square wave signal and a second square wave signal. The current mode logic gate is configured to deliver a third square wave signal at a first level and a fourth square wave signal at a second level when the first and second square wave signals are simultaneously at their first levels and the first square wave signal is ahead of the second square wave signal.
