For the measurement of physical quantities, analog sensors are usually used, which provide a proportional voltage signal from the output value. An analog-to-digital converter (ADC) is required to process this measurement data at the system level. Depending on the requirements, there are various converter topologies that differ in parameters such as sampling rate, resolution or current consumption. In addition to a high resolution, the converter topology based on the sigma-delta principle also offers the advantage of noise shaping. This shifts the interfering quantization noise spectrally to higher frequencies, which increases the signal-to-noise ratio. This makes this ADC topology particularly suitable for sensor signals with slow to medium rates of change.
The objective of this work is to compare different realization variants of sigma-delta ADCs and to implement a suitable topology based on a previously defined specification in a 180 nm CMOS technology.

WHAT TO DO:

  • familiarisation with the topic & literature research
  • comparison and contrast of different circuit topologies
  • creation of a specification based on an application example
  • selection and implementation of a suitable circuit concept

WHAT TO BRING WITH YOU:

  • advanced studies in the field of electrical engineering
  • Knowledge of analogue circuit technology
  • motivated and self-driven way of working
