When are CMOS devices preferred?
A)When power consumption is a consideration.
B)When much smaller spacing between output frequencies is necessary.
C)When stability is directly governed by the stability of the reference input.
D)When synthesizer frequency range is determined by the range of frequencies over which the VCO can operate.

Question

Quizplus · Accepted Answer

CMOS devices have low power consumption compared to other technologies, making them a preferred choice in applications where power consumption is a consideration.

Answer: D
 CMOS devices are commonly used in voltage-controlled oscillators (VCOs) in frequency synthesizers. The frequency range of the VCO determines the overall range of frequencies that can be generated by the synthesizer. Therefore, CMOS devices can be preferred when the synthesizer frequency range is determined by the range of frequencies over which the VCO can operate.
