ABSTRACT:
An amplifier is operated with a low power source voltage and has a reference voltage of 1.25 V or less. The temperature characteristic of the amplifier is controllable. The amplifier comprises substantially similar circuits and constants on its left and right sides under a condition that a voltage source is not connected to an input terminal, except that a diode-connected transistor is provided. Paying attention to the left-side circuit, the circuit which has the diode-coupled transistor having a forward voltage and resistors 22 and 23, is expressed by an equivalent circuit by the (Ho)-Thevenin theorem.
