In this thesis, a low-power, high-accuracy BJT-based temperature sensor is proposed, which consists of two main parts: a BJT-based dual-mode front-end (DMFE) and a tracking Delta-Sigma-Modulator (DSM). The front-end employs vertical PNP transistors, which, compared to NPNs, exhibit fewer non-idealities when biased at nA-level currents. The...

Kastratović, Sanja (author)
This thesis presents the design of a low-power, sub-1V, BJT-based temperature sensor. It is based on a capacitively-biased (CB) BJT front-end, in which capacitors are discharged across diode-connected BJTs to obtain proportional-to-temperature (PTAT) and complementary-to-temperature (CTAT) voltages. These voltages are then digitised by a...

Quantum computers, mainly rely on quantum bits (qubits), which need to be operated at cryogenic temperatures. With the need for systems with thousands or even millions of qubits, the challenges of wiring and scalability become more apparent. To address this, several studies focused on the idea of fully integrated cryogenic controller systems. It...

Thermal feedback has been proven to enhance user experience in human-machine interactions. Yet state-of-the-art thermal technology has focused on the single finger or palm in static contact, overlooking dynamic and multi-finger interactions. The underlying challenges include incompatible designs of conventional interfaces for providing...

In this work, a highly linear temperature sensor based on a silicon carbide (SiC) p-n diode is presented. Under a constant current biasing, the diode has an excellent linear response to the temperature (from room temperature to 600°C). The best linearity (coefficient of determination ${R}^{{2}}$ = 99.98%) is achieved when the current density...

This article presents a sub-1 V bipolar junction transistor (BJT)-based temperature sensor that achieves both high accuracy and high energy efficiency. To avoid the extra headroom required by conventional current sources, the sensor’s diode-connected BJTs are biased by precharging sampling capacitors to the supply voltage and then discharging...

Temperature sensors are widely used in industrial production, national defense and military fields. The traditional temperature sensors normally operate in a limited temperature range no more than 200 °C, which cannot be used for extreme high temperature detections. In this paper, a thermal protection method for the sensing graphene membrane...

In recent years, there has been a growing interest in investigating the potential of emerging memristor (MR) devices for gas sensing applications, particularly at room temperature. This article reports on a planar Au/reduced graphene oxide (rGO)/Au memristive hydrogen sensor, fabricated on a cost-effective cyclic olefin copolymer (COC)...

This paper presents a novel technique for dark current compensation of a CMOS image sensor (CIS) by using in-pixel temperature sensors (IPTSs) over a temperature range from −40 °C to 90 °C. The IPTS makes use of the 4T pixel as a temperature sensor. Thus, the 4T pixel has a double functionality, either as a pixel or as a temperature sensor....

Driving by the increased demand for hermetic packaging in the more than Moore (MtM) roadmap, a Cu nanoparticle sintering-enabled hermetic sealing solution was developed with a small-size sealing ring. The developed technology simplifies microfabrication and requires less surface roughness using a sinterable Cu nanoparticle paste. A 50μm size...

Due to the precise lithography and highly pure silicon used in IC technology, thermal-diffusivity (TD) temperature sensors can achieve high accuracy without the need for trimming. TD sensors employ electrothermal filters (ETFs) to measure the thermal diffusivity of silicon, i.e. the rate at which heat diffuses through silicon, which is a well...

Quantum computers exploit the quantum behavior of quantum bits (qubits) that are typically operated at cryogenic temperature. Qubits require an electronic control interface. Nowadays, such classical electronic controllers use bulky instruments operated far fromthe qubits outside the cryostat. To run practical quantum algorithms, thousands to...

Grubor, Miloš (author)
This thesis describes the design of a digital backend for a resistor-based temperature sensor realized in a 180nm CMOS process. The sensor’s analog frontend outputs a bitstream at 500kHz, which is then decimated and linearized with the help of 3 different polynomials, whose coefficients are obtained after a calibration process. A polynomial...

This article presents a 16-MHz RC frequency reference implemented in a standard 180-nm CMOS process. It consists of a frequency-locked loop (FLL) in which the output frequency of a digitally controlled oscillator (DCO) is locked to the frequency-phase characteristic of a Wien bridge RC filter. Since it is made from on-chip resistors and...

Temperature sensors that can operate in high-temperature and harsh environments are highly desired. However, this is a great challenge for sensing materials to operate under extreme working conditions because of oxidation and/or corrosion at high temperature. In this study, polymer-derived SiAlCN ceramics were prepared as sensing materials to...

Superheated nanodroplet (ND) vaporization by proton radiation was recently demonstrated, opening the door to ultrasound-based in vivo proton range verification. However, at body temperature and physiological pressures, perfluorobutane nanodroplets (PFB-NDs), which offer a good compromise between stability and radiation sensitivity, are not...

This letter describes an NPN-based temperature sensor that achieves a 1-point trimmed inaccuracy of ±0.15 °C (3σ) from -15 to 85 °C while dissipating only 210 nW. It uses a dual-mode frontend to roughly halve the power consumption of conventional frontends. First, two NPNs are used to generate a well-defined PTAT bias current, then this...

This thesis presents an energy-efficient high-accuracy temperature sensor that combines a BJT front-end with a continuous-time readout circuit. Its front-end is based on PNP transistors, which, compared to NPNs, are more widely available in CMOS processes and less sensitive to stress. In this design, proportional-to-absolute-temperature (PTAT)...
