A microphone is usually connected to an amplifier.
Usually output of an amplifier is a voltage ,...but in case of Operational Transconductance Amplifier ,Iout (current ) is the output. This feature, makes it useful for Electronic control of amplifier gain .

Operational amplifiers are usually bought as an I.C., but they may be constructed with discrete components too.
An instrumentation amplifier is made out of 2 or 3 operational amplifiers.
An op-amp, or OPerational AMPlifier, is simply a pre-built transistor amplifier circuit on a self-contained integrated circuit chip (usually one chip holds multiple op-amps)
Operational amplifiers are usually bought as an i.c., but they may be constructed with discrete compenents too. By the way, since i.c. means integrated circuit, your "ic circuit" reads as "integrated circuit circuit".

A programmable gain amplifier (PGA) is a electrical circuit that allows the controller (user, machine) to adjust its transfer function so as to provide larger or lesser voltage gain. Usually it is a simple circuit, using an operational amplifier with negative feedback. In the negative feedback loop, several resistors and switches open and close, in order to achieve the desirable gain.
A: an operational amplifier has two input A+ and a - input feeding to a base of a transistor ideally both diodes are matched with a current source to make them equal so basically they are both balanced or virtually at the same potential increasing one potential to one will inversely effect the other. usually these junctions are transistor base to emitter but it could that one is just a plain diode working on the exponential curve of the diodes
Army civilians usually gain operational experience where
With a common emitter amplifier it's the emitter that is usually grounded.
