| 摘要 | A transmission circuit includes a driver circuit that includes: a transistor to regulate output impedance, and a switching circuit that is connected to the transistor to regulate output impedance and switches an output polarity for differential output; and a bias circuit that includes: a first replica circuit including another transistor corresponding to the transistor to regulate output impedance, the bias circuit generating a gate voltage so as to make a current-voltage characteristic of the transistor to regulate output impedance correspond to a first output impedance value, and supply the gate voltage to a gate of the transistor to regulate output impedance. | ||

| 主权项 | 1. A transmission circuit comprising: a driver circuit that includes: a first transistor configured to regulate output impedance, anda switching circuit that is connected to the first transistor and configured to switch an output polarity for differential output; and a bias circuit that includes: a first replica circuit including a second transistor corresponding to the first transistor, the bias circuit being configured to generate a gate voltage so as to make a current-voltage characteristic of the first transistor correspond to a first output impedance value, and supply the gate voltage to a gate of the first transistor. | ||
