Two tantalum load resistors are heated by an input signal, while the temperature at a fixed distance is recorded on chip with a differential temperature sensing bridge. An integrated differential to single-ended stage amplifies the bridges differential voltage and provides an output voltage proportional to the input power of the detector. The thermal resistance and capacitance between the load resistor and the sensing cell act as a low pass filter in the electrical regime. Based on this concept, a detector chip has been designed, which has been analyzed in thermal simulations. The realized detector has been characterized on-chip and bonded to a microwave substrate for a system performance estimation. Its input impedance is tuned to 50 Ohms and measured matching is better than −15 dB from 150MHz to 110 GHz. With a low supply voltage of 1.5V and its active area of around 80×36µm2, the detector is suitable for an integrated power measurement solution.","PeriodicalId":349922,"journal":{"name":"2017 IEEE Radio Frequency Integrated Circuits Symposium (RFIC)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133764036","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 idea is based on shaping and optimizing the maximally efficient power gain (GME) of the circuit using a pair of internal/external feedback mechanisms.

A 195 GHz fundamental oscillator is designed in a 55 nm SiGe process (ƒmax ≃ 340 GHz), which achieves a significantly higher DC-to-RF efficiency (15.3%) among all reported oscillators working above ƒmax/3 of their active devices. The oscillator generates a peak power of 4.5 mW (6.5 dBm) with the best phase noise of −82.3 dBc/Hz and the best FoM of −197 dBc/Hz measured at 100 KHz offset frequency, which is the best phase noise and FoM among all CMOS/SiGe mm-Wave oscillators.

Therefore, an ultra-wideband IQ signal generation concept for driving a vector adder, which produces the desired phase shift in each channel of a MIMO phased array radar system, has been developed. The classic concept to generate wideband quadrature signals that uses a frequency doubler and a static frequency divider brings a 0°/180° phase uncertainty at the dividers outputs which makes this concept useless when using multiple TX-channels at once like in beamforming MIMO phased array radars. Therefore, the classical concept has been enhanced with two possible solutions which are presented in this work.
