ABSTRACT:
A current mode transmitter includes a first sink current path, through which a current flows from an output port according to a first bias voltage, a charge error canceller, which supplies a current from a high power supply voltage to a current control port in response to an input signal and counteracts a variation of a second bias voltage in response to an inverted input signal, which has an opposite polarity to that of the input signal, and the second bias voltage, and a second sink current path, which sinks current supplied from the output port in response to the second bias voltage and the inverted input signal, the second sink current path being controlled by the current control port. The input signal and the inverted input signal are complementary.
