    abstract = {This paper presents a systematic comparison of integrated transformer structures realized in a 28 nm bulk CMOS technology and characterized up to the millimetre-wave frequencies. First, the rectangular versus octagonal coil shapes are compared. Next, different transformer routing realizations using various magnetic coupling mechanisms are examined: interleaved transformers using lateral coupling, stacked ones using vertical coupling and symmetrical transformers using the combination of both coupling mechanisms. Finally, the comparison is repeated for different turn ratios: 1:1, 1:2 and 2:2. The electrical properties of the transformers, such as self-inductance, quality factor, self-resonance frequencies and mutual coupling coefficient are analysed. Advantages and disadvantages of these structures are discussed with regard to their applicability in various active circuits. One of the main targets is to obtain the best transformer’s electrical parameters for a given fixed area and given metallization option. The structures are measured up to 70 GHz. On-chip interconnects are de-embedded and the devices are compared to the models simulated by EM field solver.

    abstract = {3GPP introduced new specifications for low data rate applications, due to the IoT sector and also the enormous amount of connected devices. This standards should reduce overhead, increase coverage and reduce power consumption in addition to an increasing capacity. This paper focuses on power consumption measurements of the current existing standards e.g. LTE and makes a comparison with the new Narrowband-IoT standards. Also an evaluation on timing parameters and different modes during the transmission is given. Finally this paper helps to decide which standard provides the best benefit for a certain application.},
