CMOS opened the door for many if not most of the properties needed for today’s highly integrated circuits and low power portable and mobile devices. This really couldn’t happen until the speeds and ...

The circuit has been designed using a single CMOS integrated circuit of model 4069 to produce a frequency that is twice of the input signal by functioning as a frequency doubler. Frequency – a measure ...

In previous columns we’ve looked at TTL and CMOS logic devices in isolation. Things start to become interesting if we wish to use TTL and CMOS components in the same circuit. In previous columns we’ve ...
