Abstract

This paper introduces a new hybrid E/F power amplifier for
subcutaneous applications. The proposed design is based on Amplitude Shift
Keying (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.
