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.

Why it's free to use
- Filed October 19, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 19, 2019.
