The CFA has the useful property that when power is shut off, the input simply passes to the output with little loss. This avoids the need for RF bypass switching in the event of failure. Two CFAs can be connected sequentially with only one powered; if it fails, power can be removed from the primary tube and applied to the secondary as a backup.
The current-feedback operational amplifier (CFOA or CFA) is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback operational amplifier (VFA). The CFA was invented by David Nelson at Comlinear Corporation, and first sold in 1982 as a hybrid amplifier, the CLC103.

A bypass switch (or bypass TAP) is a hardware device that provides a fail-safe access port for an in-line active security appliance such as an intrusion prevention system (IPS), next generation firewall (NGFW), etc. Active, in-line security appliances are single points of failure in live computer networks because if the appliance loses power, experiences a software failure, or is taken off ...
In computer science, control-flow analysis (CFA) is a static-code-analysis technique for determining the control flow of a program. The control flow is expressed as a control-flow graph (CFG). For both functional programming languages and object-oriented programming languages , the term CFA, and elaborations such as k -CFA, refer to specific ...
Continuous flight augering (CFA), also known as auger cast piling, is a technique used in construction to create a concrete deep foundation. Description [ edit ]
Research into the next generation of commercial jet engines, high-bypass ratio turbofans in the "10-ton" (20,000 lbf; 89 kN) thrust class, began in the late 1960s. Snecma (now Safran), who had mostly built military engines previously, was the first company to seek entrance into the market by searching for a partner with commercial experience to design and build an engine in this class.
A lock bypass is a technique in lockpicking, of defeating a lock through unlatching the underlying locking mechanism without operating the lock at all. It is commonly used on devices such as combination locks, where there is no natural access (such as a keyhole) for a tool to reach the locking mechanism. Because the mechanism itself is not ...
