Abstract
An amplifier includes in series, between high and low supply voltages, first, second, and third transistors. The first transistor is an input transistor of a first current mirror, and the second transistor is an output transistor of a second current mirror. The control electrode of the third transistor forms an inverting input of the amplifier. The amplifier further includes, in series between the high and low supply voltages, fourth, fifth, and sixth transistors. The fourth transistor is an output transistor of the first current mirror, and the fifth transistor is an input transistor of the second current mirror. The control electrode of the sixth transistor forms a non-inverting input of the amplifier. The output current of the amplifier is provided by a seventh transistor. The amplifier is applied to form a band-gap voltage generator having a small number of circuit branches.
