Answer is Right!
Answer is Wrong!
The correct answer is C. Two.
A CMOS inverter has two regions of operation: the linear region and the saturation region.
In the linear region, the output voltage is between the power supply rails and the input voltage is greater than the threshold voltage of the MOSFETs. In the saturation region, the output voltage is either close to the positive or negative power supply rail and the input voltage is less than the threshold voltage of the MOSFETs.
The linear region is not typically used in CMOS inverters because it is not very efficient. The saturation region is the most common region of operation for CMOS inverters.
The following is a brief explanation of each option:
- Option A: Three. This is incorrect because there are only two regions of operation for a CMOS inverter.
- Option B: Four. This is incorrect because there are only two regions of operation for a CMOS inverter.
- Option C: Two. This is the correct answer because there are only two regions of operation for a CMOS inverter.
- Option D: Five. This is incorrect because there are only two regions of operation for a CMOS inverter.
