This paper presents a regenerative sampling oscillator for the simultaneous regeneration of phase and amplitude, which enables highly efficient QAM schemes in the mm-wave range to reach multi-Gb/s data rates. A nonlinear model is derived to study the phase regeneration and the startup behavior of the oscillator and is simulated in CADENCE. A cross-coupled circuit is fabricated in a 0.13-μm SiGe BiCMOS...
This paper presents an experimental study of a green wireless powered communication network (WPCN), where sensors with wireless power transfer (WPT) capabilities are located at known positions and an energy transmitter (ETx) is employed to wirelessly power the uplink between the sensors and the access point (AP). By monitoring and measuring the charging time that the sensors require to power their...
