Design of a floating window 8-bit level crossing analog-to-digital converter

Project (M.S., Electrical and Electronic Engineering)--California State University, Sacramento, 2019.

In modern biomedical applications, the power consumption of electronic circuits is of utmost importance. Generally these applications involve measuring low frequency signals over long periods of time. A level crossing analog-to-digital converter (LC-ADC) is perfect for this application because a data conversion is triggered only when there is a significant change in the input signal. This allows the circuit to consume very little power during the typically long periods of inactivity. This project explores the design of a new LC-ADC that consumes less power than conventional LC-ADC designs. Simulations of the new proposed LC-ADC design were performed over process, supply voltage, and temperature (PVT) variations to verify functionality and determine power consumption.
