Abstract:
1. A receiver for receiving a signal comprising a common mode signal and a differential signal, the receiver comprising: a first voltage-to-current converter that converts a first voltage input of the signal to a first current; a second voltage-to-current converter that converts a second voltage input of the signal to a second current; and a current subtractor that provides a difference current of the first and second currents that is indicative of the differential signal; wherein each of the first and second voltage-to-current converters comprise: a voltage input; a reference voltage node; a resistor coupled between the voltage input and the reference voltage node, that produces an input current corresponding to a difference between a voltage at the voltage input and a voltage at the reference voltage node divided by the resistance of the resistor; and a current source coupled to the reference voltage node, the current source providing a reference current to be combined with the input current.
