This study proposes a design of a maximum power point tracking (MPPT)‐based DC–DC boost converter for an radio frequency (RF) energy harvester. The MPPT technique has been implemented in the converter using an adaptable load tracking mechanism with variable input RF power to meet the supply voltage tolerance limits. The proposed MPPT scheme is implemented using a sample‐and‐hold circuit in the tracking loop of the DC–DC boost converter. The complete energy harvester system prototype has been realised in a 130 nm standard complementary metal‐oxide‐semiconductor (CMOS) process. The footprint of the proposed converter circuit is much smaller compared to similar designs reported in the literature making it applicable for wearable and implantable biomedical applications.
