  • Coupling Transformer - an overview

    Sean Gold, William Jett, in Analog Circuit Design, Volume Three, 2015. Driving transformer-coupled loads. Transformer coupling is frequently used to step up transmission line signals. Voltage signals amplified in this way are not constrained by local supply voltages, so the amplifier's rated current rather than its voltage swing usually limits the power delivered to the load.
