Design of a Cryo-CMOS Smart Temperature Sensor

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...

A High-speed Amplifier And Loop Filter Architecture For A GHz Sampling Sigma-Delta ADC

This thesis presents the design and implementation of a low power 3rd-order loop filter and a low power, compact, high-speed inverter-based amplifier designed in 28nm HPC for a GHz sampling Σ∆ modulator.<br/>In the earlier design, the size of the pMOS in an inverter was found to be nine times larger than the nMOS which is not practical to obtain a...

High Speed and Wide Bandwidth Delta-Sigma ADCs

This thesis describes the theory, design and implementation of a high-speed, high-performance continuous-time delta-sigma (CT??) ADC for applications such as medical imaging, high-definition video processing, and wireline and wireless communications. In order to achieve a GHz clocking speed, this thesis investigates excess loop delay...

Fully Integrated Analog Front-end for a 2-electrode ECG device

Cardiovascular diseases are leading cause of deaths worldwide. With increasing graying population and limited health infrastructure there is a need for portable and implantable ECG devices to diagnose these diseases early on. In general an ECG device requires three or more electrodes, which need to be applied to the body via a gel, to obtain a...
