The series-shunt configuration is preferable due to the balanced performance of high isolation and power handling capability. Conventionally, such configuration suffered from phase fluctuations over the input power drive making extra phase compensation necessary for proper system operation. Theoretical analysis by an equivalent circuit model revealed that the phase fluctuation was primarily caused by the capacitance of the devices in the series arm. We thus proposed a design using the single-pole-double-throw (SPDT) configuration as an example featuring minimum phase variation over a very wide RF input power range. Compared to the conventional one, the proposed design achieved at least a reduction of over 10° at 28 GHz in phase variation over a wide input power range up to the input 1-dB compression point (\u0000<inline-formula> <tex-math>$P_{1,text {dB}}$ </tex-math></inline-formula>\u0000). To our knowledge, this is the first series-shunt type SPDT switch study achieving the minimum phase variation over wide input power levels.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"34 11","pages":"1251-1254"},"PeriodicalIF":0.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595125","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}

A time amplifier with automatic gain control is proposed to provide a wide detectable range during acquisition and a high gain at lock condition. The charge-pump gain is also adaptively tuned to ensure that the overall loop gain is constant for robust operation. The PLL includes a 12-phase inverter-based coupled ring oscillator. Instead of placing all the delay cells in one ring, the multiple phase outputs are achieved by capacitive coupling of two identical ring oscillators. The proposed double-ring coupled ring oscillator provides additional output phases without scarifying the output frequency and phase noise. The inductorless PLL is implemented in 22-nm FDX CMOS technology with a core area of 0.0253 mm2 and achieves up to 23-dB in-band phase noise improvement to −113.1 dBc/Hz and a measured integrated jitter of 1.274 ps at 2.4 GHz. The 12-phase ring PLL consumes 8.18 mW from a 0.8-V power supply and achieves a measured PLL FoM of 229 dB.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"34 11","pages":"1275-1277"},"PeriodicalIF":0.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142595092","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}
