Complementary Current-Injection Field-Effect Transistor
A CiFET is a pair of Complementary iFETs connected at their Drain with a Common Gate and support 2 Non-Inverting Current Injection Ports (iPort)
Characteristic (Rin) Resistance
Absorbs iPort Input Energy
Constant Channel Current
Very High Speed
Wide Dynamic Range
Reacts to iPort Input Current
NiFET (N-type Current Field Effect Transistor)
CiFET is 2 iFETs Connected with a Common Gate and 2 Current Injection Ports (iPort)
iPort Operation is similar to a BiPolar transistor: a base current is input into a Vbe.
The CiFET iIn is also valid in either direction as well as zero; yielding no crossover discontinuity.
All input modes are precisely linear & algebraically sum.
The width to length ratios of the source and drain channels can be adjusted for different performance optimizations.
~3*Wider P-channels can balance out P-to-N mobility differences for electrical symmetry.
Abundant carrier sub-surface conduction provides high-speed with low resistance and low surface trap noise, without speed-limiting carrier velocity saturation. Ultra-Linear transfer function is a result of complementary cancellation of higher-order terms.
