    Abstract: Disclosed is a transistor having a first region of a first conductivity type for injecting charge carriers into the transistor and a laterally extended second region of the first conductivity type having a portion including a contact terminal for draining said charge carriers from the transistor, wherein the first region is separated from the second region by an intermediate region of a second conductivity type defining a first p-n junction with the first region and a second p-n junction with the second region, wherein the laterally extended region separates the portion from the second p-n junction, and wherein the transistor further comprises a substrate having a doped region of the second conductivity type, said doped region being in contact with and extending along the laterally extended second region and a further contact terminal connected to the doped region for draining minority charge carriers from the laterally extended second region. An amplifier circuit and IC including such transistors are also disclosed.

    Abstract: An ESD protection circuit comprises a series connection of at least two protection components between a signal line to be protected and a return line (e.g. ground), comprising a first protection component connected to the signal line and a second protection component connected to the ground line. They are connected with opposite polarity so that when one conducts in forward direction the other conducts in reverse breakdown mode. A bias voltage source connects to the junction between the two protection components through a bias impedance. The use of the bias voltage enables the signal distortions resulting from the ESD protection circuit to be reduced.
