Abstract :
This paper presents a new dual-slope-based time-interleaved quantizer architecture. Time information between interleaved quantizer channels is utilized to perform time-domain delta modulation. This technique decouples the conversion rate of dual-slope quantizers from their input voltage amplitude without the need for extra timing phases or dedicated hardware.
