Abstract
Conference Title: 2017 IEEE 60th International Midwest Symposium on Circuits and Systems (MWSCAS) Conference Start Date: 2017, Aug. 6 Conference End Date: 2017, Aug. 9 Conference Location: Boston, MA, USA This paper proposes a highly sensitive RF-to-DC power converter with an extended dynamic range that is designed to operate at the medical band 433 MHz and simulated using 0.18 μm CMOS technology. Compared to the conventional fully cross-coupled rectifier, the proposed design offers 3.2× the dynamic range. It is also highly sensitive and requires −18 dBm of input power to produce a 1 V-output voltage when operating with a 100 kΩ load. Furthermore, the proposed design offers an open circuit sensitivity of −23.4 dBm and a peak power conversion efficiency of 67%.
