This paper presents a process for full-3d circuit and RF passive component fabrication based on two main steps: additive manufacturing of the plastic or ceramic substrate, through a stereolitographic 3d printer, and a copper electroless plating metallization process. The metallization results are discussed in terms of resistivity, comparing them to the State-of-the-Art on 3d printedelectronics. The capabilities and accuracy of the process have been demonstrated anddiscussed through the fabrication of conical inductors.

We present several contributions of our test system to detect multiple targets with the direct time-of-flight technique. With a precise time-to-digital-converter it is possible to capture the time-of-flight of a short light pulse reflected by a target with high temporal resolution. Based on this technique we can relate the single events to its resulting distance and separate the different objects.

The intrinsic sensitivity limit of Stimulated Raman Spectroscopy (SRS) is given by the shot noise of the optical stimulation. However, it is seldom reacheddue to the electronic noise of the front-end amplifier and the intensity fluctuations of the laser source. Here, we present and test a low-noise pseudo-differential amplifier, for Raman spectroscopy applications, able to compensate the common-mode fluctuations given by the laser and to reach a sensitivity better than 10 ppm thanks to the lock-in technique.

A firmware encryption for embeddeddevices can prevent the firmware from being read out to clone the device to a counterfeited one or to steal the intellectual property of the software developer. Also the integrity is ensured to hinder an attacker from manipulating the firmware to a malicious one. In this work, a cryptographic concept to implement a Secure Boot functionality using the intrinsic properties of a specific hardware device is shown. After describing the physical Unclonable Function and the cipher used for the implementation, the key generation algorithm is explained. Further, the function of the crypto-module inside the system architecture and the secure boot sequence are described.

This paper presents simulation results of a CMOS switching mode power amplifier (SA) in a 65 nm technology with adjustable output voltage swing. The output stage is built in a stackeddesign to prevent dielectric breakdown of the transistors. Inverters at the top and bottom of the stack provide the supply voltage for the stack. The configuration offers a variable output voltage swing between one, two or three times the nominal transistor supply voltage. This paper demonstrates the advantages over a power amplifier with fixed output levels for signals with high peak to average output power ratio (PAPR).

The simulation of the passage of particles through matter using Monte Carlo methods is broadly used in the development of particle detectors for high energy physics experiments. To develop the readout electronics for the Compact Muon Solenoid (CMS) experiment at CERN, and to assist the design of the on-detector ASICs, a simulation framework was build capable to link the physics Monte Carlo simulations platforms with an industry standard EdA simulation tools. This contribution focuses on the implementation of the simulation framework based on the System Verilog language and the Universal Verification Methodology (UVM). The simulation results that guided the development of the ASICs and the choice of the final architecture are presented.

This paper presents the design and measurements of a fully differential charge sensitive amplifier operating in the frequency range from 7 Hz to 300 kHz. In comparison to the typically employed single input transistor topology, the shown differential approach greatly simplifies the suppression of common mode noise. The theory of the fully differential charge sensitive amplifier and analytical rules for the correct sizing of the feedback resistor and the input transistor are derived. Finally a double-cascode-amplifier is presented, achieving an equivalent noise charge of 114 elementary charges rms in the 7 Hz to 300 kHz frequency band at 5.4 pF differential detector capacitance. The amplifier is realized in a 0.35 mu m standard CMOS technology and consumes 26.4 mW at 3.3 V supply voltage.
