Op amps also have input current noise on each input. For a VFB op amp, the inverting and non-inverting input current noise are typically equal, and almost always uncorrelated. Typical values for wideband VFB op amps range from 0. The input current noise of a bipolar input stage is increased when input bias-current cancellation generators are added, because their current noise is not correlated, and therefore adds in an RSS manner to the intrinsic current noise of the bipolar stage.
This is because the input stage in a CFB op amp is usually operated at a higher current, thereby reducing the emitter resistance and hence the voltage noise. The input current noise of CFB op amps tends to be larger than for VFB op amps because of the generally higher bias current levels.
The inverting and non-inverting current noise of a CFB is usually different because of the unique input architecture, and are specified separately.
In most cases, the inverting input current noise is the larger of the two. This can simplify the calculations using the formula, assuming the correct decisions are made regarding the sources to be included and those to be neglected.
The sources which dominate the output noise are highly dependent on the closedloop gain of the op amp.
Notice that for high values of closed loop gain, the op amp voltage noise will tend be the chief contributor to the output noise. At low gains, the effects of the input current noise must also be considered, and may dominate, especially in the case of a CFB op amp.

Radio tubes are valves. Philips - Transistor History - Google Sites ; By Valvo celebrated producing a million OC70 transistors and the first RF junction transistor: the OC45 announced in the autumn of , matched by Telefunken who brought out the OC, both transistors being for intermediate frequency use.
