ABSTRACT:
A transmission system, circuit and method are provided herein for converting differential signals into low duty cycle distortion, single-ended signals that are insensitive to variations in PVT and input common mode voltage. In one embodiment, the signal translation circuit includes an input stage for receiving a pair of differential input signals and producing one or more differential output signals; an intermediate stage for combining the one or more differential output signals into a pair of complementary signals from which a common mode voltage is detected; and an output stage for generating a single-ended output signal that switches from a first value to an opposite value when one of the complementary signals is substantially equal to the common mode voltage.
