The flash type converter is the simplest and the fastest type of analog to digital converter. The entire digital output word is present just after the propagation delay time of comparators and the encoding logic gates. A typical conversion time of a three-bit flash analog to a digital converter is 33 ns. The circuit of a three-bit flash analog to digital converter shown in figure 1, needs just three comparators and no combinational logic circuitry. Circuit Description of Three Bit Flash Analog to Digital Converter In this circuit, the reference…
