Design Considerations of a Matching Circuit for Low Power Wake-Up Receivers

Abstract

This study explores the analysis and the design of a passive input matching circuit used in low power wake-up receivers. The results show that by using a combination of on-chip components, package parasitics, and an off-chip inductor, a passive gain of 23.23 dB can be achieved at 915 MHz while achieving a return loss of -15 dB.
