The 4–20 mA convention was born in the 1950s out of the earlier highly successful 3–15 psi pneumatic control signal standard, when electronics became cheap and reliable enough to emulate the older standard electrically. The 3–15 psi standard had the same features of being able to power some remote devices, and have a "live" zero.
The scale current is proportional to the cross-sectional area of the diode. Continuing with the symbols: V T {\displaystyle V_{\text{T}}} is the thermal voltage ( k T / q {\displaystyle kT/q} , about 26 mV at normal temperatures), and n {\displaystyle n} is known as the diode ideality factor (for silicon diodes n {\displaystyle n} is ...
Specifically, leakage current and threshold voltage do not scale with size, and so the power density increases with scaling. This eventually led to a power density that is too high. This is the "power wall", which caused Intel to cancel Tejas and Jayhawk in 2004. [9] Since around 2005–2007 Dennard scaling appears to have broken down.
The complex impedance of a series choke is effectively part of the load impedance, so that lightly loaded circuits have increased ripple (just the opposite of a capacitor input filter). For that reason, a choke input filter is almost always part of an LC filter section, whose ripple reduction is independent of load current. The ripple factor is:

Commensurate lines are transmission lines that are all the same electrical length, but not necessarily the same characteristic impedance (Z 0).A commensurate line circuit is an electrical circuit composed only of commensurate lines terminated with resistors or short- and open-circuits.
Adaptive voltage scaling (AVS) is a closed-loop dynamic power minimization technique that adjusts the voltage supplied to a computer chip to match the chip's power needs during operation. Many computer chips, especially those in mobile devices or Internet of things devices are constrained by the power available (for example, they are limited to ...
