Which of the following statements is NOT true for CMOS inverters?
1
These clock generators offer a wide frequency range (1 Hz to in excess of 15 MHz).
2
CMOS inverters are commonly used to build sinusoidal - wave oscillators for generating clock signals.
3
These clock generators offer good stability, operation over a wide supply voltage range (3 - 15 V).
4
These clock generators offer low power consumption and an easy interface to other logic families.
