WebbParallel flash converters use a bank of comparators that compare the input voltage to a set of reference voltages across a resistor network. The voltages start at a value equal to that for one-half the least-signifi-cant bit (LSB) and increase in equal voltage incre-ments equivalent to one LSB for each comparator. As Webb1 maj 2004 · This paper introduces a single-ended non-offset-cancelled flash ADC architecture, the “Threshold Inverter Quantizer” (TIQ). 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 …
