<p>In this paper, we present a novel, piezoelectric actuator driver topology that combines high-voltage actuator driving in the range of -50 V- to +100 V with piezoelectric reliability. The output waveform is generated by a novel capacitor clamping circuit (patent# PCT/EP2016/066134) with programmable rise-and fall times implemented in a 0.35 um high-voltage bulk CMOS technology optimized for capacitive light-load (2 nF- to 8 nF) operation. The novel piezoelectric actuator driver consists of a negative voltage generator and a degradation regulator integrated onto a single chip. The smart driver electronics is optimized towards reliable piezoelectric operation by taking fatigue and electrical overstress into account. The novel piezoelectric actuator driver is the first step towards self-regulated electrical compensation of piezoelectric actuator degradation which promises increased actuator lifetime and reliable operation.</p>

<p>In this paper we present a structural analytical model for a capacitive micromachined ultrasonic transducer (CMUT), based on a sacricial release fabrication process and comprised of electro-mechanical plate actuators transferring their motion to a coupling roof structure on top. The structure features a larger average displacement compared to conventional designs at lower<br>
operational frequencies. Low operational frequencies in the range of 40 kHz to 1MHz are benecial for airborne applications due to their frequency-dependent strong wave attenuation in air, limiting the signal-to-noise ratio. The eigenfrequency in dependence of the roof mass is calculated analytically and lumped elements, which can be used in equivalent circuits, are extracted. In addition, nite element analyses utilizing a shell-beam model are conducted. Experimental results, based on digital holographic microscopy, reveal the usability of the deduced model within an uncertainty of 8 %. The developed dimensionless form of the analytical model can be used for future design purposes.</p>

<p>Organic light emitting diodes (OLED) are promising candidates offering in optical sensor applications to detect different gas compositions and excitable optical marker groups in chemical and biological processes. They enable attractive solutions for monitoring the gas phase composition of e.g., dissolved molecular oxygen (O2) species in bio reactors or excitation of fluorescent markers. In this work, we investigate different OLED devices for biomedical applications to excite the fluorescent dye rhodamine 6G (R6G). The OLED devices are built in top emission geometry comprising a distributed Bragg reflector (DBR) acting as optical mirror. The OLED is optimized to provide a very narrow emission characteristic to excite the R6G at 530 nm wavelength and enabling the possibility to minimize the optical crosstalk between the OLED electroluminescence and the fluorescence of R6G. The DBR includes a thin film encapsulation and enables the narrowing of the spectral emission band depending on the number of DBR pairs. The comparison between optical simulation data and experimental results exhibits good agreement and proves process stability.</p>

<p>The reaction times of environmental sensor units are potentially improved by the use of micropumps. Those<br>
micropumps require miniaturized driver electronics which generate dual-polarity high voltage pulses optimized to drive<br>
light, capacitive load piezoelectric micropumps. This paper presents a novel micropump driver consisting of a DC/DC<br>
converter circuit that is based on a combination of a boost converter and a charge pump. This combination generates<br>
asymmetric high voltages on two individual synchronous output nodes from a 5-V supply. Through reduction in the number of<br>
coils this method supports the overall system shrinking and allows a high level of chip integration. Compared to state-of-theart<br>
miniaturized drivers, the presented topology allows singleended and differential micropump driving at higher voltage<br>
levels (-100 V/+150 V). By connecting the micropump differential to the converter output, the maximum voltage can<br>
be increased to 250 V for capacitive micropump loads of up to 200 nF. The converter topology was validated by measurement.<br>
The presented novel, miniaturized micropump driver topology allows micropump integration into mobile devices for new fields<br>
of sensor applications with rapid reaction times.</p>

<p>This paper demonstrates the feasibility of a nonisolated single inductor asynchronous boost converter for driving piezoelectric actuators up to 100 V. The realized device is using a novel 700V bulk 0.35um CMOS XFAB technology. The control scheme for the boost converter, working in discontinuous conduction mode (DCM) only, is using a peak-current control scheme with adaptive off-time. For an input voltage range between 2.5V and 6V and output voltage up to 100V it achieves a peak-efficiency of 70% by using a die area of 22.9 mm<sup>2</sup>.</p>

<p>The significance of transistor degradation due to aging mechanisms such as BTI or HCI has increased significantly with the continuous scaling down of CMOS technologies and their presence in safety-critical systems. In order to deliver the reliable systems that the industry currently demands, it is necessary to apply aging simulations in IC design projects. However, the capabilities that are available strongly depend on the EDA environment and tools. In this paper we present the work done in a case study to characterize and model NBTI and HCI degradation for X-FAB’s XU035 technology, and we discuss a methodology developed to implement and integrate user-defined aging models for circuit level simulation with consistent results across different design environments.</p>
