APPARATUS FOR RECEIVING OR TRANSMITTING VOLTAGE SIGNALS

Apparatus useful for receiving or transmitting voltage signals might include a current generator having first and second inputs and configured to generate a current flow between first and second outputs responsive to a voltage difference between its first and second inputs. The apparatus might further include a feedback amplifier having a first input connected to the first output of the current generator, a second input connected to the second output of the current generator, a first voltage signal node connected to its first input through a first resistance, and a second voltage signal node connected to its second input through a second resistance, wherein a first inverter is connected in parallel with the first resistance, a second inverter is connected in parallel with the second resistance, and a pair of cross-coupled inverters are connected between the first voltage signal node and the second voltage signal node.
