Large-Signal Characterization of SOI MOSFETs Using NVNA and Active Load-Pull
Dr. Manuel Pulido, Andres Zarate, pSemi Corp. A Murata Co.
In this talk, pSemi(TM) Modeling Group will present SOI MOSFETs device characterization and validation using a combination of mixer-based NVNA and new active load control (ALC) PNAX feature from Keysight(TM). Measurement result summary will be shown of what works while highlighting instrumentation challenges encountered so far during critical non-linear measurement points.
Discussion: Use of NVNA in device characterization and model validation
Large Signal Characterization of Dual-Input PAs
Chenyu Liang(1) and Thaimi Niubo Aleman(2),(1) (PhD students)
(1)The Ohio State University, (2) CICESE Ensenada
This presentation will discuss the testbeds used at OSU to characterize the large-signal response of new types of dual-input outphasing PAs for both CW and modulated excitations. Three different testbed solutions (LSNA, FPGA or NVNA based) will be presented. The procedures used for aligning the phase, calibrating the amplitude and synchronizing the modulation of the two input signals will be reviewed for both CW or LTE/OFDM modulated measurements. Measured results on the PA efficiency versus outphasing angles and PA linearization will be presented for dual-input Doherty, Chireix and Hybrid PAs.
