Design of efficient hybrid E F power amplifier for biomedical purposes

الملخص EN

This paper introduces a new hybrid E/F power amplifier for subcutaneous 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 power amplifier combines the tuning network circuits and uses a control unit to control a selectable switch to choose the desired amplifier.

The Amplitude Shift Keying modulator is proposed to supply the proposed hybrid amplifier with approximately constant DC voltage.

The proposed power amplifier aims to provide an appropriate power to power the implantable devices and reduce the hardware of the subcutaneous devices depending on the specific applications.
