This paper introduces a new hybrid E/F power amplifier forsubcutaneous applications. The proposed design is based on Amplitude ShiftKeying (ASK) modulation technique with Industrial Scientific Medical (ISM)band operating at 135 kHz to avoid the tissue damage. The Hybrid E/F poweramplifier combines the tuning network circuits and uses a control unit tocontrol a selectable switch to choose the desired amplifier. The Amplitude ShiftKeying modulator is proposed to supply the proposed hybrid amplifier withapproximately constant DC voltage. The proposed power amplifier aims toprovide an appropriate power to power the implantable devices and reduce thehardware of the subcutaneous devices depending on the specific applications
