ABSTRACT:
A high speed receiver circuit is disclosed with a high supply voltage and operable with other circuits operating at a low supply voltage. The receiver circuit comprises first and second differential input signals controlling first and second current switches. It also includes a top current supply connected to the high supply voltage for providing a current to be passed either through the first current switch and a first bottom current supply or the second current switch and a second bottom current supply. Further included are first and second resistors connected to the low supply voltage and in a series with the first or second bottom current supplies respectively. First and second differential output signals are produced at a point between each pair of the resistors and the bottom current supply. A common mode voltage of the first and second differential output signals is lower than the low supply voltage.
