This work presents a spin torque nano-oscillator (STNO) based binary frequency shift keying (BFSK) modulation schema implemented on a printed circuit board (PCB). Maximal input data rate reaches 20 Mbit/s. Depending on the STNO used, carrier frequency can range from 1 to 10 GHz. Both DC and AC currents flowing through the STNO can be tuned between 0 to 4 mA. Using one magnetic tunnel junction (MTJ)...
Among various emerging technologies, Nano Magnetic Logic (NML) is the one that may represent, in future, a replacement of CMOS for many reasons. In the last years, researchers have been conducting experiments to understand the properties and potentialities of this novel technology. NML can be used to build any kind of logic circuit and, because of its intrinsic magnetic nature, it is perfectly suitable...
We present the solution-based synthesis of silver nanowires (AgNWs) with an aspect ratio over 400 in a short growth time of 20 min. The addition of potassium chloride (KCl) during the growth regulates the supply of silver atoms and leads to an agglomerate-free and well-dispersed solution. Via a facile and scalable deposition technique, i.e. spray-coating, the AgNWs are deposited to transparent electrodes...
Artificial neural networks (ANN) have become a powerful tool for machine learning. Resistive memory devices can be used for the realization of a non-von Neumann computational platform for ANN training in an area-efficient way. For instance, the conductance values of phase-change memory (PCM) devices can be used to represent synaptic weights and can be updated in-situ according to learning rules. However,...
Thanks to the recent development of resistance-switching memories, crosspoint array has become an attractive architecture to obtain high-density storage. However, crosspoint arrays suffer from sneak current paths and voltage drops on interconnection lines, which may lead to various challenges such as excessive leakage power, write failure, write disturbance, and insufficient read margin. In this paper...
In this paper an interface circuit for MOX gas sensor is presented. It is based on a resistance-to-frequency converter and improves existing solutions in term of performance (offset) and power efficiency. The resistive range covered is 100Ω-1MΩ, with an equivalent 8-bit precision in a total measurement time of 1 second. This corresponds to a dynamic range of about 128dB. Power consumption and design...
A CMOS image sensor architecture that uses a cellular automaton for the pseudo-random compressive sampling matrix generation is presented. The image sensor employs inpixel pulse-frequency modulation and column wise pulse counters to produce compressed samples. A common problem of compressive sampling applied to image sensors is that the size of a full-frame compressive strategy is too large to be...
This paper presents the development of a mixed-signal multi-functional system for current measurement and electrical stress detection. The system is composed of a tracking ADC and a double range (a coarse and a fine one) current-steering DAC. The coarse range, designed for the full-scale input values [0A:108A], has a 5b resolution and it is used for the stress detection feature. The fine range is...
TIGER (Turin Integrated Gem Electronics for Readout) is a mixed-mode front-end ASIC developed to readout the new inner tracking detector of the BESIII experiment, carried out at BEPCII in Beijing. The detector is planned to be installed during the 2018 upgrade and features an innovative three-layer triple-CGEM (Cylindrical Gas Electron Multiplier) with analog readout. The ASIC comprises 64 channels,...
A pair of completely integrated capless preamplifiers (not requiring external capacitance) for MEMS microphones are presented. The devices exploit specific circuit solutions to implement a proper dc biasing of the pre-amplifier and a low frequency (< 1 Hz) high-pass pole. The two solutions adopted are a based on a transistor in the off state (OTP) and a switched-resistor (SRP), respectively. Since...
This paper presents a design approach for the output matching networks (OMN) required in continuous class B/J power amplifiers (PA). Design equations of the OMN are derived and used to design a class-B/J PA that covers the frequency band from 2.2 GHz to 3.45 GHz. The PA uses the LDMOS device available in the 130 nm SOI technology from STMicroelectronics. Simulation results show that the PA has an...
In this paper, a broadband, inductorless noise-canceling low-noise transconductance amplifier is presented. The proposed circuit is suitable for TV White-Space applications. It has a single-ended input, eliminating the need for an external balun, and a balanced output, which can be followed by a double-balanced current-switching mixer for high IIP2. The circuit is based on a common-gate stage with...
This paper presents a fully integrated class-A mode Differential Power Amplifier (DPA) on a thin silicon substrate intended for being embedded into flexible electronic foil systems. A high-speed and cost-effective 95 GHz-fmax, 0.25 μm SiGe:C technology (IHP process SGB25V) is used. RF performance of DPA has been evaluated with the pre- and post-thinning measurement results at die level. The behavior...
This paper presents a spectral peak estimation technique for tight resources systems. Based on a basic zero-crossing (ZC) frequency estimator, an enhanced ZC frequency estimation technique is proposed. The technique conducts a tunable band-pass filter (BPF) that relies on a primary estimation from another ZC block. In principle, the filter reduces the noise content of the signal, hence increasing...
A secondary frequency modulated continuous wave (FMCW) RADAR with two-way ranging can be used for indoor and outdoor positioning with high precision and accuracy. However, non-line-of-sight (NLOS) conditions lead to multipath effects that have a negative impact on the quality of ranging and positioning measurements, if the spectral analysis is not able to detect the correct line-of-sight (LOS) path...
A concept for a slope shaping gate driver IC is proposed, used to establish control over the slew rates of current and voltage during the turn-on and turn-off switching transients. It combines the high speed and linearity of a fully-integrated closed-loop analog gate driver, which is able to perform real-time regulation, with the advantages of digital control, like flexibility and parameter independency,...
