Abstract
An amplitude setting circuit for setting an amplitude level of its output signal corresponding to an input signal. By setting a current flowing through a first diode-connected transistor (Q) and a current flowing through a first drive transistor (Q) to be in a predetermined relationship, variation with temperature in potential at a first connection point of the first drive transistor (Q) and a first conductivity-type transistor (M) is removed, and by setting a current flowing through a second diode-connected transistor (Q) and a current flowing through a second drive transistor (Q) to be in a predetermined relationship, variation with temperature in potential at a second connection point of a second conductivity-type transistor (M) and the second drive transistor (Q) is removed.
