A first linear voltage to current converter includes an MOS current source transistor with its gate connected to a source of fixed voltage, used to feed the source of an MOS follower transistor. A second linear voltage to current converter includes a bipolar current source transistor with its base connected to a source of fixed voltage, used to feed the source of an MOS follower transistor. A differential pair includes in each leg a bipolar current source transistor with its base connected to a source of fixed voltage feeding the source of an MOS follower transistor. A differential amplifer includes two circuit legs including these transistor circuits.
