Differential output circuit and communication device
A differential includes first and second current mirror circuits that provide the gates of slave transistors with gate voltages of master transistors via a voltage follower where a slew rate at a rise time is equal to a slew rate at a fall time. Thus, when the master current is increased or decreased, an incremental change in slave current and a decremental change in slave current are symmetrical with each other. The use of such current mirrors in a differential manner leads to no generation of common mode noise even in these changes.
