Today, 18:51KlausST replied to a thread 14 bit adc output to 5 bit data conversion in VHDL in PLD, SPLD, GAL, CPLD, FPGA DesignHi, Maybe I misunderstand.. But if you want to generate 5 (linear. Not logarithmic like u-law, A-law) bits from a 14 bit ADC ... then just use...3 replies | 157 view(s) -
Today, 06:51KlausST replied to a thread Measure inl of an ADC in cadence in Analog Integrated Circuit (IC) Design, Layout and FabricationHi, This topic is not new, thus do an internet search "INL measurement ADC" to find documents. I see documents from adc manufacturers, but I...4 replies | 142 view(s)
