4. Operational amplifier - Wikipedia

   en.wikipedia.org/wiki/Operational_amplifier

   An operational amplifier (often op amp or opamp) is a DC-coupled electronic voltage amplifier with a differential input, a (usually) single-ended output, [1] and an extremely high gain. Its name comes from its original use of performing mathematical operations in analog computers .

6. Norton amplifier - Wikipedia

   en.wikipedia.org/wiki/Norton_amplifier

   The LM3900 was introduced in the mid 1970s, and was designed to be an easy to use single supply op amp with comparable input bias currents (~30nA) to other bi polar op-amps of the time period (LM741, LM324), while having rail to rail output and a much higher gain bandwidth product(2.5MHz).

7. Operational transconductance amplifier - Wikipedia

   en.wikipedia.org/wiki/Operational_trans...

   The operational transconductance amplifier (OTA) is an amplifier that outputs a current proportional to its input voltage. Thus, it is a voltage controlled current source (VCCS). Three types of OTAs are single-input single-output, differential-input single-output, and differential-input differential-output (a.k.a. fully differential), [ 1 ...

9. Gain–bandwidth product - Wikipedia

   en.wikipedia.org/wiki/Gain–bandwidth_product

   For transistors, the current-gain–bandwidth product is known as the f T or transition frequency. [4] [5] It is calculated from the low-frequency (a few kilohertz) current gain under specified test conditions, and the cutoff frequency at which the current gain drops by 3 decibels (70% amplitude); the product of these two values can be thought of as the frequency at which the current gain ...
