Abstract
An amplifier arrangement includes a first amplifier powered by a pair of lower voltage power supplies, a second amplifier powered by a pair of higher voltage power supplies and a drive control device. This amplifier arrangement has both current and voltage gain larger than one. The drive control device includes a regulating device adapted to switch off the first amplifier based on the output signal of the amplifier arrangement, and at least one current link and at least one voltage controlled current source. The transition between the operation of the first and second amplifiers is thereby controlled by the values of the currents of these at least one current links and the at least one voltage controlled current sources.
