Patent ID: 7368992

Claim:
An electronic push-pull amplifier having an output stage, which output stage further has at least one sourcing active output device for sourcing a sourcing current to a load through a sourcing current path, and at least one sinking active output device for sinking a sinking current from the load through a sinking current path, comprising a sourcing current sense resistor for facilitating sensing of the sourcing current through the output stage sourcing current path of the push-pull amplifier, the sourcing current sense resistor being located in the output stage sourcing current path, a sinking current sense resistor for facilitating sensing of the sinking current through the output stage sinking current path of the push-pull amplifier, the sinking current sense resistor being located in the output stage sinking current path, a quiescent current control means for controlling a quiescent current through the output stage sourcing current path and sinking current path in response to the least one of the sourcing current and the sinking current through the output stage sourcing current path and sinking current path, respectively, whereby output impedance and crossover distortion are reduced.
