to miniature implantable sensor systems such as [1]. To recharge batteries of such systems, wireless power transfer is a popular option since it is non-invasive. However, there are two main challenges: 1) strict safety regulations of incident power on human tissue; 2) small coil size for better biocompatibility. These issues reduce the received power at the coil, make it difficult to obtain sufficient power for implanted devices, and call for high power-efficiency (ηP)-transfer techniques, especially at very low received power levels. Most conventional wireless power receivers are composed of a rectifier for ACDC conversion, followed by a DC-DC converter or linear regulator (Figure 21.5.1). In this approach the input power (PIN) at the receiver coil (LRX) must be high
