This paper presents a concept for a compact multiharmonic load transformation network (MHLTN), appropriate for a fully integrated differential dual-band PA design in an RF front-end transmitter. The proposed MHLTN was applied to implement a dual-band class-E PA based on finite DC-feed inductance in a 130 nm CMOS process for GSM1700 and LTE2500 operation. With a dual-band input matching network, simulation results have shown peak power added efficiency (PAE) and peak output power of more than 57% and 27 dBm, respectively, at both bands. The designed PA is also able to cover a wide frequency range. From 1.4 GHz to 2.7 GHz, output power is above 25 dBm and PAE is higher than 50 %.","PeriodicalId":122918,"journal":{"name":"10th IEEE International NEWCAS Conference","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114736260","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}

This paper presents the architecture of a fully autonomous Integrated Circuit which efficiently harvests energy from low frequency mechanical stresses. This circuit uses a high voltage piezoelectric transducer and provides energy to a storage element (battery or capacitor) at lower voltage (2.8 to 3.4V). We propose an innovative way to extract the electrostatic energy by using a modified Flyback topology and multiple magnetic transfers. Measurements show that our solution increases the energy transfer with a gain of 15% compared to the classical technique. We show that this work improves the efficiencies of both power and control stages. Finally, the control circuit of the Flyback converter will perform a self-starting operation from an empty energy storage element and is currently being designed in AMS0.35 CMOS technology.","PeriodicalId":122918,"journal":{"name":"10th IEEE International NEWCAS Conference","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132008999","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}

These regulators will provide best voltage switching and power delivery when they can be integrated on the same chip with the microprocessor. However, their on-chip implementation is challenging because of low power-conversion efficiency and noisy output due to inductive element. Furthermore, inductors are difficult to be implemented on the chip, because they occupy valuable space due to their large size and introduce many parasitic effects. In this paper we investigate several techniques to replace inductors in a voltage regulator. The purpose is to identify the most suitable option to design physical inductor-less regulator. From primary observation it appears that active circuit elements based inductor can replace inductor in on-chip regulator design.","PeriodicalId":122918,"journal":{"name":"10th IEEE International NEWCAS Conference","volume":"339 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134229176","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 new method, called ETBR-GPU, first performs sampling-like reduction on the original circuit matrices where the frequency domain responses at different frequency points can be calculated in parallel on multicore CPU. After the reduction, the reduced circuit matrices, which are dense but well suitable for GPU's data parallel computing, are simulated on GPU. Such reduction based simulation technique is very amenable for parallelization on the hybrid multicore and GPU platforms, where coarse-grained task-level and fine-grained lightweight-thread level parallelism can be both exploited. The proposed method is very general, since it can analyze any linear networks with complicated structures and macromodels, and it does not assume some structure properties in order to build problem-specific preconditioners, as many iterative solvers do. Experiments show that the new method achieves about one or two orders of magnitude speedup when compared to the general LU-based simulation method on some recently published IBM power grid benchmark circuits.","PeriodicalId":122918,"journal":{"name":"10th IEEE International NEWCAS Conference","volume":"2012 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129852942","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}

As a typical example of the NV-LIM circuit, we apply it to motion-vector extraction.

Analyzing periodic root-loci can provide useful design information, which is not available from the existing circuit simulation tools. Although the numerical QZ algorithm can be used to generate periodic root-loci, this paper proposes an alternative symbolic computation method for repeated pole computation. It is demonstrated that the Muller algorithm can be used for finding the dominant periodic roots of a characteristic polynomial with periodic coefficients, whose efficiency is superior to the matrix-based numerical QZ method. Other advantages of symbolic root-locus analysis also are explored by applying the proposed method to the analysis of two oscillator circuits.","PeriodicalId":122918,"journal":{"name":"10th IEEE International NEWCAS Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129741280","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}
