The invention relates to an apparatus and method for low output voltage expansion in a current transmitter. An integrated circuit includes a current mode transmitter. The current mode transmitter includes a first resistor and a second resistor. The resistance of the first resistor is adjusted by measuring the resistance, generating a resistance trimming code based on the measured resistance, and writing a first resistance trimming code to the first register. The resistance of the second resistor is adjusted by generating a second resistance trimming code based on the first resistance trimming code and writing the second resistance trimming code to the second register. 本公开涉及电流发送器中低输出电压扩展的设备和方法。一种集成电路包括电流模式发送器。电流模式发送器包括第一电阻器和第二电阻器。通过测量电阻、基于测得的电阻生成电阻修整代码并将第一电阻修整代码写入第一寄存器来调整第一电阻器的电阻。通过基于第一电阻修整代码生成第二电阻修整代码并将第二电阻修整代码写入第二寄存器来调整第二电阻器的电阻。
