The almost universal choice in semiconductor power amplifiers is for a unity gain output stage, and specifically a voltage follower. Output stages with gain are not unknown, 1 but they are not common.

Figure 1 shows a voltage follower with one QOA and with offset adjust. Figure 1. Circuit of DC buffer-follower with paralleled QOA and with external offset adjust The four OAs are paralleled and the ...

An engineer asked me for help when he encountered what appeared to be strange phenomenon while testing a prototype circuit in the system. He saw “mysterious” clipping distortion of the signal at the ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

CMOS current mirrors are pivotal in modern electronic circuitry, providing accurate current replication that is essential for biasing, amplification and active loading in a myriad of integrated ...
