There are two groups of classic circuits: those which have served us well in the past, but have been superseded by better designs, and those which are still in use, perhaps with updated components. In ...

CMOS devices have large input impedance with input currents on the order of 0.01nA. Adding feedback circuitry can result in a latch-like device that can be used to store bits, and also operate in a ...

A custom comparator IC that has fast response time and hysteresis protects a car's engine control unit from failures on monitored peripherals that create high current conditions. In most modern cars, ...
