A high-resolution, enhanced SNR and controllability are achieved with a proposed architecture. By controlling timing between the transmit (TX) pulse and sampling clock of the receiver, echo pulses from targets are received and recovered. The TX pulse can adjust its spectrum occupancy by changing impulse shape. The 4-channel sampling receiver consists of a low noise amplifier, track and hold samplers, integrators, and a cascaded triple delay locked loop. The embedded control logic allows the radar to enhance the SNR of the received pulse using an averaging technique, and to operate at multiple reception modes. The real-time radar system measurements show that echo pulses are recovered with ≥100-psec range resolution while consuming 80 mW from 1.2-V of Vdd. An indoor human walking trace is successfully recorded.

A measurement technique based on the conventional S-parameter measurement is developed to measure the mismatch behavior at high frequencies (HFs). First, besides the typical de-embedding, the bondpad mismatch is subtracted statistically from the capacitance mismatch measurement. Second, a semi-empirical methodology using physical parameters, such as window CD and vertical doping, is developed to model the measured AC mismatch behavior for transistors of different size. Finally, a systematic procedure is proposed to extract the mismatch parameters, which can be used in the SPICE Monte-Carlo mismatch simulation. The proposed mismatch modeling methodology is validated on an industrial 0.35μm RF BiCMOS process. The proposed model fits the mismatch characteristics of the key AC parameters, such as CBE, CBC, and fT at different current densities. The model also scales well with geometry for the transistors with sizes useful for RFIC application.","PeriodicalId":203521,"journal":{"name":"2013 IEEE Radio Frequency Integrated Circuits Symposium (RFIC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128499051","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}

High-power, broadband power amplifiers (PA) operating in the D-band (110-170 GHz) are essential towards implementation of broadband frequency multiplier chains at sub-mmWave frequencies.

A staggered tuning approach where the peak gain of the individual or group of individual stages are tuned at offset frequencies is used for broadband operation. In the 135-170 GHz, the small signal gain for the PA is 14-17 dB and the saturated output power (Psat) varies from 5-8 dBm and the output referred 1 dB compression point (P1dB) varies from 1-6 dBm over this frequency range.
