Noise-tolerant switched-capacitor time-delay measurement system for micro-fluidic flow sensing

The delay between an electrical signal and its delayed replica is measured by a switched-capacitor sum of absolute differences analog method. The core circuitry is implemented in a custom integrated circuit. We have proven with simulations and measured results that the system is capable of measuring...

Beschreibung
Zusammenfassung:	The delay between an electrical signal and its delayed replica is measured by a switched-capacitor sum of absolute differences analog method. The core circuitry is implemented in a custom integrated circuit. We have proven with simulations and measured results that the system is capable of measuring the delay even in the presence of considerable added noise.
