Timing-based integrated sensor interfaces: Hype or promise?

Summary form only given. The scaling of VLSI technology results in reduced supply voltages, hence jeopardizing the voltage swing and signal-to-noise ratio achievable by analog integrated circuits. An alternative is to take advantage of the increased speed resolution of faster CMOS technologies, and to replace traditional voltage-mode processing by time-based circuits. This presentation will explore the potential and fundamental limitations in time-based versus voltage-based analog integrated circuits for application in sensor interfaces.
