Introduction to CMOS
Let’s talk about the characteristics of an ideal logic family. It should dissipate no power, have zero propagation delay, controlled rise and fall times, and have noise immunity equal to 50% of the logic swing...
CMOS Schmitt Trigger Applications
The Schmitt trigger has found many applications in numerous circuits, both analog and digital...
CMOS Oscillators
This note describes several square wave oscillators that can be built using CMOS logic elements. These circuits offer the following advantages...
Transmission Line Effects of High Speed CMOS
Because of 54HC/74HC high-speed CMOS’s short propagation delays and fast rise and fall times, you must understand its transmission-line behavior when driving lines as short as even a foot or two...
Layout Guidelines for CMOS Circuits
The need to reduce a logic system’s noise emission is becoming ever more apparent with the increased use of high-speed electronics...
Understanding Latchup
Latch-up has long been a bane to CMOS IC applications; its occurrence and theory have been the subjects of numerous studies and articles...
Minimizing Ground Bounce
As system designers begin to use high performance logic families to increase system performance, they may run into new problems which previously did not raise concern when lower performance devices were utilized...
