Temperature greatly affects the performance of integrated circuits, and so temperature sensors are often necessary to ensure reliable operation and stable performance. The goal of the work described in this thesis is to realize a temperature sensor in CMOS technology that can be produced at low cost. In the first step, a temperature sensor is...

This thesis describes the implementation of a phase-domain readout system for a thermal-diffusivity (TD) based temperature sensor. Such sensors measure the phase shift of an electro-thermal filter (ETF), which exhibits a near-linear dependency on absolute temperature. The phase shift is measured by a phase-domain delta-sigma modulator (PD-DSM)....

Advanced Systems-on-Chip (SoCs) exhibit significant self-heating and require thermal management to prevent overheating. Sensors for this application should be not only small so that they can be placed ubiquitously, but they should also achieve moderate accuracy and resolution within 1 ms so that the die temperature can be monitored with...

Peng, Jida (author)
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...

In this study, we combined finite element method (FEM) based on Ansys and Noesis Optimus software to investigate the effect of bump structures and loading conditions on the electromigration properties of solder bumps in WLCSP. A numerical model considering current density, vacancy concentration, stress and temperature was utilized to calculate...

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...

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...

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...

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...

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...

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....

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...

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...

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...
