What is it about?
The TIQ is based on a CMOS inverter cell, in which the voltage transfer characteristics (VTC) are changed by systematic transistor sizing. As a result, a significant improvement of speed and reduction of area and power consumption is achieved

Why is it important?
No resistor or capacitor array requirement in analog part of a Flash ADC design
Perspectives
This technique have been popular day by day in Flash ADC designs. Some designers employ this technique in other ADC architectures as well. ADC designers have even modified TIQ as can be seen in the literature. I had difficulty in advertising this technique during my PhD study before 1999. But now I am so happy to see its popularity from citations of it every year.
