A Current Conveyor Implementation of Double Differential Amplifier for Active Electrodes
Carla Caruso, Alfio Dario Grasso, Federico N. Guerrero, Gaetano PalumboABSTRACT
This work presents two transistor‐level solutions to implement a double differential (DD) amplifier by using a current conveyor, which can be used as front‐ends in standalone active electrodes for superficial electromyography (sEMG) applications. Currently published DD amplifiers highlight the advantages of using second‐generation current conveyors to achieve simplified topologies, but they do not provide transistor level implementations. In this work, two solutions are presented and analyzed in detail.
