Introducing m.o.s.t. devices

Unlike the original transistor, which is current operated, the metal-oxide-semiconductor transistor is voltage operated, and its operating characteristics are so similar to those of the thermionic valve that well established circuit-design techniques applicable to the valve can be applied to the design of circuits using the m.o.s.t. At the same time, the familiar inherent advantages of solid-state electronic devices are apparent. Its valve-like features also make it very acceptable to those engineers who were taught electronics based on the thermionic valve as the active element.
