dc.description.abstract | This thesis explores the use of the ring amplifier in 28 nm FDSOI. The intended use is as
a residue amplifier in a SAR (successive approximation register) assisted pipeline ADC.
The specifications for the ADC are 13 effective bits at a sampling rate of 50 MS/s. This
thesis is a continuation of Sivert Krøvel s thesis work from 2016, where he used SAR
VerilogA-models and an ideal amplifier. This thesis continues to use the SAR-models, but
the amplifier is replaced. The ring amplifier is a relatively new amplifier topology that
takes advantage of time domain properties to achieve higher speed and energy efficiency
than it is possible to reach using traditional operational amplifiers.
This project does not manage to create an amplifier that meets the specifications, due to
issues regarding noise and speed. The amplifier along with the ADC models gives 10.3
effective bits at a sampling rate of 10 MS/s. | |
