We compare different algorithms for multi-parameter circuit optimization using the Smith Tube. Comparison is performed between gradient, pattern, and simplex searches in 2, 3, 4, and 5 dimensions. While simplex performs very well in lower dimensions, its usefulness significantly decreases for higher dimensions. Gradient search is shown through these comparisons to provide the best results in five dimensions for the types of searches and starting points examined in this work.","PeriodicalId":227955,"journal":{"name":"2016 Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125904145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inclusion of tunable phase shifters and Mach-Zehnder interferometer (MZI) couplers in the filter's rings and front-end provides comprehensive tuning to compensate for variations in ring resonance frequency, coupling ratio, and phase mismatches.

The monolithic PA, designed in 0.35-μm SiGe BiCMOS technology with through-silicon via (TSV) using continuous wave (CW) load-pull, passes the stringent LTE spectrum emission mask (SEM) at average linear POUT = 23.5/23.1/23.1 dBm with 48.0/45.2/45.0% PAE for LTE 5/10/20 MHz inputs. The adjacent channel leakage ratios ACLR1/ACLR2 exhibit opposite trends vs. increasing signal BW at POUT below compression (P1dB = 22.3 dBm), while past compression ACLR1/ACLR2 increase with larger BW, with some ACLR2 asymmetry at 10/20 MHz. Lowering the supply voltage has a larger effect on ACLR degradation than higher signal BW. The data suggests that static CW load-pull data is useful for PA design even for 16QAM modulated signal but cannot accurately predict SiGe PA's linearity performance.","PeriodicalId":227955,"journal":{"name":"2016 Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121743335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The oscillator was designed in a 1P6M SMIC 180nm CMOS standard logic process. The post simulation with layout parasitic parameters shows the oscillator's tuning range is 0.25GHz to 5.82GHz. Over the tuning range, the phase noise varies from -105dBc/Hz to -115dBc/Hz @10MHz offset. The maximum power consumption is 31mw from a 1.8V supply.
