CMOS inverter is used as SPDT switch in resistor DAC and is connected to the op-amp line. Find the output of CMOS, if the input applied is 1

Correct Answer: Resistance is connected to input line
When Qbar =1, it makes transistor Q1-ON and Q2-OFF. The output of the CMOS inverter is 0v, connecting the resistance R1 to ground.
