Darlington amplifier
WebJan 17, 2006 · A 5-V-supply-operated Darlington amplifier conquers overhead-voltage issues to deliver temperature and supply stability while maintaining efficient operation. Kevin W. Kobayashi Wideband Darlington RF gain blocks are commonly used in wireless and wire-line applications. WebDarlington pairs essentially place one transistor as the common-collector load for another transistor, thus multiplying their current gains. The base current through the upper-left transistor is amplified through that transistor’s emitter, which is directly connected to the base of the lower-right transistor, where the current is again amplified.
