Analysis of Different Interface Circuits,esonance. Whereas due to its linearity, the analysis of the purely resistive load can be done straightforward using simple Laplace transformations, the analysis of the full-wave rectifier load and the SECE load requires complex math to get general closed-form expressions for the output power. Since

Theory of the Proposed PSCE Circuit, path can produce significant power losses which reduce the harvested power. The techniques presented in the following have the goal to diminish these undesired power losses. Besides numerical analysis, a linear approximation is discussed, allowing to make a statement about the superiority of these

In constrast, higher power consumption can be allowed for blocks which have to react faster, but can be deactivated most of the time. In the following, the operation principle of the circuit blocks is explained individually in detail. Wherever possible, the blocks are grouped by their

Performance Analysis of the PSCE Chip,rformance analysis of the PSCE chip, describing in detail how the output power and the overall chip losses can be measured. Simulations are used to extensively analyze the different loss mechanisms within the chip. After that, the operation limits of the PSCE chip are discussed, ending up with the c
