The proposed RF I/O realizes image rejection (IR) function at RX side without loss penalty by using an on-chip transformer, which enables a power amplifier (PA) to achieve an 8dBm-output power without requiring additional supply. Moreover, the proposed method enhances Q value of the transformer, thus further improving the RX's NF. By selecting interference-sparse marine radar's band of 3.1GHz as image frequency, the image tolerance of RX in actual environment can be remarkably improved. The RX achieves 6.0dB NF, 14dB image rejection ratio (IRR), −105dBm sensitivity with 15mW power consumption. The TX achieves 8dBm output power with 22% efficiency with a single supply. The TRX satisfies BLE 5.0 standard, and achieves link budget 113dB which is the best value known to date.","PeriodicalId":355210,"journal":{"name":"ESSCIRC 2018 - IEEE 44th European Solid State Circuits Conference (ESSCIRC)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128984093","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 proposed pseudo-digital control loop consists of a latched comparator, a 2X charge pump and a RC network. It detects the output voltage and provides a continuous gate control signal for the power transistor by charging and discharging the RC network. Fast transient response is achieved due to the source follower structure of the power NMOS, with a small output capacitor and small occupied chip area and without consuming large quiescent current. The proof-of-concept design of the proposed PD-LDO is implemented in a 0.18-J.1m CMOS process. The minimum supply voltage is 0.7 V, with a dropout voltage of 100 mV and a maximum load current of 100 mA. Using only 20 pF of on-chip output capacitor and 10 MHz comparator clock frequency, the undershoot is 106 mV with 90 mA load current step and 150 ns edge time.

Yet, we have seen that in spite of the large investments, these systems today are still not superseding human driver limited safe driving capability - even with human supervision. There are also multiple other applications of such technologies, that are not about driving on streets, for industrial, infrastructure, home and health applications, where “robotic moving vehicles” have similar sensing and behavior needs. This presentation highlights the motivations behind the journey from advanced driver assistance systems (ADAS) to full autonomy of vehicles and what are the key driver sensing skills and behaviors that need to be replaced to complete a safe trip. The human drivers carry many “learnings” about the scenes and behaviors they observe from other drivers or pedestrians and this learning to a great extent can compensate for some inaccuracy of sensing by use of anticipation of behavior. The sensing in autonomous cars also has the burden of ensuring “sound” actions with a limited depth of learning, and hence multiple sensing of 3D surround scenes is essential for this robustness. Redundancy in such systems is also essential to ensure self-checking, and graceful exit when partial sensor failure happens. Active and passive sensing with propagating waves, be it optical, mmWave or ultrasonic are key elements for surround sensing. Other sensing modalities to predict automobile behavior, orientation, inclination, inertia and road surface are all essential for decision making. Moreover, without any driver, which is an ultimate goal of AV, the vehicle needs to interact with passengers or other “cargo” which opens another set of sensing needs to ensure their safety and desires. The presentation tries to highlight the key requirements of such sensing modalities, the key gaps that exist today in the capability of each sensing technology, and directions of where research in sensors can help to enable fully safe autonomy. Finally, while robust multi-modal sensing systems are essential, they are not sufficient for the success of such complex systems. The fusion of information of the sensing data, the continuous learning needed for every type of autonomous system, and the communication are all elements of such a robotic vehicle and play a major role in reaching the robustness, sound decisions and accuracies needed. It is becoming evident, that such a need will help drive semiconductor industry for years to come with all the demands and value it creates and hence, the role of research in closing the need gaps is essential for such growth.","PeriodicalId":355210,"journal":{"name":"ESSCIRC 2018 - IEEE 44th European Solid State Circuits Conference (ESSCIRC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133113815","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}
