摘要:
A high-speed differential signaling logic gate includes a 1st input transistor, 2nd input transistor, complimentary transistor, current source, a 1st load, and a 2nd load. The 1st input transistor is operably coupled to receive a 1st input logic signal, which may be one phase of a first differential input signal. The 2nd input transistor is coupled in parallel with the 1st input transistor and is further coupled to receive a 2nd input logic signal, which may be one phase of a 2nd differential input signal. The complimentary transistor is operably coupled to the sources of the 1st and 2nd input transistors and to receive a complimentary input signal, which mimics the other phase of the 1st differential logic signal and the 2nd differential logic signal. The current source sinks a fixed current from the 1st and 2nd input transistors and the complimentary transistor. The 1st load is operably coupled to the drains of the 1st and 2nd input transistors to provide a 1st phase of a differential logic output. The 2nd load is coupled to the drain of the complimentary transistor to provide a 2nd phase of the differential logic output.
