A 2-bit flash Analog to Digital Converter (ADC) is given below. The input is \(0 \le {V_{IN}} \le \;3\) Volts. The expression for the LSB of the output \({B_0}\) as a Boolean function of \({X_2},\;{X_1},\) and \({X_0}\) is
1
\({X_0}\left[ {\overline {{X_2} \oplus {X_1}} } \right]\)
2
\(\overline {{X_0}} \left[ {\overline {{X_2} \oplus {X_1}} } \right]\)
3
\({X_0}\left[ {{X_2} \oplus {X_1}} \right]\)
4
\({\bar X_0}\left[ {{X_2} \oplus {X_1}} \right]\)
