After repeating that again for the minutes and building a similar circuit for the hour, and [Easton] had a working 4000-series 24-hour clock. The breadboard clock may not be the prettiest thing ...

First let’s look at the use of CMOS gates as memory devices. Figure 1 shows a one-bit transparent latch. A single CD4069 hex inverter can make a 3-bit latch, or if one uses a CD4050 hex buffer one can ...

However, cutting-edge CMOS has limitations in these applications. Process restrictions, inaccurate simulation models, wide parametric variance, and noisy application environments require special ...

Mostly-Analog editor Andy Turudic takes a look at the original 1963 ISSCC paper that described the world’s first CMOS process ... a differential logic inverter circuit. 4. A potential ...
