Abstract: A temperature-stable variable gain amplifier having a differential input stage coupled to a first terminal of a voltage supply generator and a second terminal of the voltage supply generator through first and second field-effect transistors whose gate terminals are connected to two bipolar transistors which are also connected between the first terminal of the voltage supply generator, through two resistors, and the second terminal of the voltage supply generator, through third and fourth field-effect transistors. Also, the third and fourth transistors have gate terminals connected into a second common control terminal, and the collector terminals of the bipolar transistors form output terminals for the amplifiers.
