Patent attributes
Aspects of the disclosure provide a circuit using digital techniques to generate a differential signal with a low skew. The circuit can include a first switching element configured to receive at least a first logic value and a second logic value, and output a first signal of the differential signal, the second logic value being different from the first logic value. Further, the circuit can include a second switching element configured to receive at least the first logic value and the second logic value, and output a second signal of the differential signal. Additionally, the circuit can include a selection signal generator coupled to the first switching element and to the second switching element, the selection signal generator being configured to provide a selection signal to the first switching element and to the second switching element, the selection signal causing the first signal to transit from the first logic value to the second logic value based on the selection signal, and causing the second signal to transit from the second logic value to the first logic value based on the selection signal.
