We just got a paper accepted at the 61st IEEE International Midwest Symposium on Circuits and Systems (MWSCAS) at the Late Breaking news session titled A Low-Power Time-Domain Comparator for IoT Applications",  This paper introduces a low-power time-domain comparator with a modified current starved inverter circuit. The proposed comparator converts the analog input voltage into a time delay that creates a phase difference between the input signal and the reference signal offering a FoM of 60 fJ/conversion step. Finally, the proposed time-domain comparator circuit is compatible with wide range of applications (i.e., internet of things (IoT) sensors and integrated DC-DC converters).
