Webthe ADC incorporates a comparator topology with zero static power—a StrongArm latch [2]–[4], for example. As explained below, the ladder’s static current is ultimately chosen accord-ing to the conversion speed. Design Issues The principal drawback of the flash ADC is the exponential growth of its “cost” as a function of resolution. The WebFlash ADCs are made by cascading high-speed comparators. Figure 1 shows a typical flash ADC block diagram. For an N-bit converter, the circuit employs 2 N -1 …

WebThe MAX1151 is a parallel flash analog-to-digital con-verter (ADC) capable of digitizing full-scale (0V to -2V) inputs into 8-bit digital words at an update rate of 750Msps. The ECL-compatible outputs are demuxed into two separate output banks, each with differential data-ready outputs to ease the task of data capture. WebOct 29, 2024 · Flash ADC is selected because of its simplest design, parallel operation and non-linearity. It exploits comparator and Thermometer to Binary (T2B) Encoder as its major components for digital conversion. The resolution is directly proportional to the requirement of comparators.
WebFeb 6, 2024 · As we designed entire ADC core by using 1.5V for encoder circuit and 0.6V for comparator circuit along with resistor ladder. Total core operating voltage is 2.1V i.e. very lesser voltage than compared to previous existing models. And also we verified entire ADC core power consumption that is very less in the form of micro watts. REFERENCES
