Soil water-content sensors based on the measurement of soil impedance are widely used for the detection of rain-fall induced slope failure and other agriculture applications. In principle, low-leakage sensors can measure soil water content down to 4%, but they require readout systems capable of generating soil excitation signals at frequencies...

Temperature threshold sensors facilitate temperature protection in microprocessors by indicating when the processor gets overheated or too cold. This thesis presents a BJT based temperature sensor with a programmable temperature threshold from -40°C to 150°C. Comparison of a CTAT voltage with a PTAT voltage gives a one-bit digital output when...

Operational amplifiers are basic building blocks of an analog system. As a system is only as good as its building blocks. There exists a constant need for developing a high-performance amplifier. Especially if they are configured as a buffer for analog front-end applications, as the system performance is highly dependent on the quality of input...

This thesis describes the design and characterization of thermistor-based electrothermal filters (ETFs) intended for use in high-accuracy CMOS temperature sensors. ETFs have been previously realized by placing an on-chip heater in close proximity to an on-chip thermopile, which then picks up the thermally-delayed signals generated by the heater....

This thesis presents an Eddy current sensor (ECS) for button readout applications. By employing a Phase-locked loop to perform a frequency readout, it was possible to significantly reduce the power consumption of the interface while achieving resolutions comparable to prior arts making it a more suitable solution for portable applications. The...

Digital isolators are devices that connect one electrical system block to another over a galvanically isolating barrier. They allow electrical systems to communicate with each other even though they may operate at vastly different potentials. They also do the job of eliminating potentially damaging ground loops between the two systems. This...

This work presents a fully differential Class D audio amplifier using 2.1MHz pulse-width modulation (PWM) frequency and 425kHz LC filter cut-off frequency to decrease the cost of off-chip components. Moreover, feedback after LC filter structure is used to attenuate LC filter nonlinearities.

This thesis proposes a novel low distortion, on-chip sine-wave generator. A low distortion input is required in many test and measurement setups for analog and mixed-signal systems, where the input signal should have less distortion than that contributed by the device under test (DUT). For conventional oscillators, there is a compromise between...

Analog to digital converters (ADCs) are critical blocks in most signal processing chains.<br/>Especially in low bandwidth applications, there exists a need to digitize signals with high resolution and accuracy, while at the same time, expending minimum energy.<br/>This thesis presents a dynamic zoom ADC for use in such applications. The zoom ADC...
